Available in PDF, EPUB and Kindle. Book excerpt: Cryomilled aluminum alloys are being developed for aerospace applications. These high-strength aluminum alloys are currently targeted for low-temperature rocket applications. This research focused on the fundamental strengthening mechanisms in these alloys. The primary sources of strengthening in cryomilled aluminum alloys are dispersion of nanocrystalline particles and ultrafine grain size that form during the cryomilling stage. Optimized thermo-mechanical processing of cryomilled powder results in an ultrafine grain size material with nanocrystalline particles. This study investigated the temperature dependence of strength and ductility in these alloys. The theoretical models predict strengthening at low temperatures and decrease of flow stress with decreasing grain size because of diffusional flow and grain boundary sliding at elevated temperatures. The results from this study show discrepancies with theoretical models. Significant work hardening was observed at room temperature in both Al-Ti-Cu and Al-Mg alloys. The strain hardening exponents suggest contributions from both direct and indirect work hardening mechanisms. At elevated temperatures, the stress-strain rate data for Al-Mg alloys can be best described by a power law constitutive relationship with a stress exponent of 5 and threshold stress. However, the activation energy is very high even after compensating for threshold approach. This indicates that dissolution of Al3Mg2 precipitates influence the deformation kinetics.

Available in PDF, EPUB and Kindle. Book excerpt: Aluminum alloys with nanocrystalline (NC) and ultra-fine grain (UFG) sizes are of interest because of their high strength - typically more than 30% stronger than conventionally processed alloys, with acceptable levels of tensile ductility - ranging from 3 - 15 %. By generating NC powders via mechanical milling in liquid nitrogen (cryomilling), a thermally stable UFG microstructure evolves during thermomechanical processing (TMP), which allows for large scale consolidation, and hence opportunity for basic studies. The constituents that stabilize the microstructure - dispersed oxides and nitrides - also contribute to the strength of the system. Careful examination of microstructures and stress-strain data generated for cryomilled pure Al and Al-Mg alloys, with various milling times and media allows strengthening mechanisms to be dissected, improving understanding of cryomilled Al alloys. Grain boundary (Hall-Petch), dispersion (Orowan), solid solution and dislocation hardening mechanisms are quantified based on experimentally developed UFG Al alloys crossing multiple investigations. Grain size variations in the materials are studied based on TMP routes, milling time and milling media. Dispersion strengthening is quantified and related to oxygen and nitrogen content in the consolidated materials. Solid solution strengthening via magnesium additions to the Al alloys is studied. And, dislocation hardening is investigated by cold rolling consolidated plates at room temperature. Additionally, the intentional incorporation of ceramic particulates, such as Al2O3 and B4C, provides the basis for analyzing systems using basic composite models. The effect of size and morphology of the particulates reinforcing the alloy to form the metal matrix composites (MMCs) is discussed in terms of specific surface area and a possible change in mechanism from load transfer to Orowan strengthening as the particulates approach nanometric scale.

Book excerpt: Recently, it was reported that nanostructured materials processed under high pressure by HPT and ECAP have an extraordinary combination of both high strength and high ductility, which are two desirable, but rarely co-existing properties. These findings indicate that high-pressure is a critical factor that can be employed to process nanostructured materials with superior mechanical, and possibly also physical, properties. It is the objective of this workshop to review our current knowledge, identify issues for future research, and discuss future directions on the processing and properties of nanostructured materials via SPD techniques, with a special emphasis on high-pressure effects. The 42 peer-reviewed papers in this book cover areas of high pressure effect on the nanostructure and properties of SPD-processed materials, fundamentals of nanostructured materials, development of high-pressure SPD technologies for commercializations, recent advances of SPD technologies as well as applications and future markets of SPD-processed nanostructured materials.

Available in PDF, EPUB and Kindle. Book excerpt: The present collection of articles focuses on the mechanical strength properties at micro- and nanoscale dimensions of body-centered cubic, face-centered cubic and hexagonal close-packed crystal structures. The advent of micro-pillar test specimens is shown to provide a new dimensional scale for the investigation of crystal deformation properties. The ultra-small dimensional scale at which these properties are measured is shown to approach the atomic-scale level at which model dislocation mechanics descriptions of crystal slip and deformation twinning behaviors are proposed to be operative, including the achievement of atomic force microscopic measurements of dislocation pile-up interactions with crystal grain boundaries or with hard surface coatings. A special advantage of engineering designs made at such small crystal and polycrystalline dimensions is the achievement of an approximate order-of-magnitude increase in mechanical strength levels. Reasonable extrapolation of macro-scale continuum mechanics descriptions of crystal strength properties at micro- to nano-indentation hardness measurements are demonstrated, in addition to reports on persistent slip band observations and fatigue cracking behaviors. High-entropy alloy, superalloy and energetic crystal properties are reported along with descriptions of deformation rate sensitivities, grain boundary structures, nano-cutting, void nucleation/growth micromechanics and micro-composite electrical properties.

Available in PDF, EPUB and Kindle. Book excerpt: Its high alloying makes it prone to solidification defects. Thus, plastic deformation is required to close shrinkage porosity, making this alloy for wrought products only. Moreover, this alloy has a limit of maximum Mg content at 1.8% as a high Mg content would form bulky Al2CuMg phase in the matrix, which has a limited solubility during solutionizing. Nanoparticles successfully reduced the solidification defects and greatly recovered the ductility of the cast alloy. In summary, this dissertation first discussed a new interface-controlled mechanism for in-situ synthesis of ceramic nanoparticles to build a solid foundation for economical nano-treating of molten metals. Then the nano-treating effects on solidification and heat treatment were systematically studied. Finally, two critical effects from nano-treating were summarized: "antibody effect" to enable scalable manufacturing of various high-strength aluminum alloys without cracking and shrinkage porosities and "vitamin effect" to improve microstructure and properties of alloys. The effects were successfully demonstrated to develop and manufacture high-performance aluminum alloys: manufacturing high-strength Al-Zn-Mg-Cu alloy, natural aging to AA7075 welds with nano-treated welding wires, and casting of high-strength Al-Cu-Mg alloys.

Available in PDF, EPUB and Kindle. Book excerpt: A critical, up to date, tutorial review and discussion of the science and technology of nanostructured metallic and ceramic materials. The focus is on the synthesis and processing of nanoparticles, the assembly and stability of nanostructures, characterization and properties, and applications. There is a growing interest in the processing of nanoparticles into consolidated bulk materials and coatings. The metastability of nanoparticles may lead to undesirable grain growth during thermally assisted consolidation or other processing routes, and the retention of nanostructures in a processed part or component continues to attract a great deal of attention. Current activity is concentrating on the deposition of nanostructured coatings using established thermal spray technology and wet chemistry methods. Naturally existing or artificially synthesized templates with unique structures and morphologies have been used to fabricate nanostructured materials with the same structural and morphological characteristics as the templates. Recent advances in characterization techniques have provided information on the structure, the surface and bulk chemistry of nanoparticles, and the structures and chemistry of exposed and buried surfaces of coatings. Contributors are drawn from Canada, France, UK, USA, Belarus, Russia and Ukraine.

Available in PDF, EPUB and Kindle. Book excerpt: High performance (hardness, strength, electrical/thermal conductivity, ductility, Young's modulus, and corrosion resistance, etc.) copper (Cu) based materials are in strong demand in industry for numerous applications. However, it has been a long-standing challenge to achieve high performance Cu by scalable and cost-effective fabrication due to the limits of traditional metallurgy. Pure Cu is very soft and improving the mechanical properties of Cu comes at great expense of electrical and thermal conductivity. The properties of traditional Cu alloys have reached certain limits. Nanotechnology enabled metallurgy provides a new pathway to achieve significant performance enhancement of Cu. The overarching goal of this dissertation is to advance the fundamental understanding of nanoparticle effects on micro/nano-structures and properties of Cu/Cu alloys, thereby overcoming the existing limits of Cu/Cu alloys. The specific research objectives are to develop effective processing methods to synthesize and disperse suitable nanoparticles in Cu/Cu alloys and to break the limits of grain refinement, phase modification, and property enhancement in Cu/Cu alloys by nanoparticles.Two ex-situ processing methods were utilized to fabricate Cu matrix nanocomposites with a wide volume fraction range of well-dispersed nanoparticles. To enable the size control of the nanoparticles and expand the choices of nanoparticles for Cu/Cu alloys, novel in-situ synthesis of nanoparticles and Cu matrix nanocomposites were developed. In-situ TiB2 nanoparticles with an average size of 65 nm in the Cu matrix were synthesized using fluoride salts as precursors and Al as the reduction agent via casting. It was also discovered that Al in molten Cu can stabilize TiB2 nanoparticles. This finding overcame the challenge of incorporating TiB2 nanoparticles into molten Cu. In addition, Cu with in-situ W nanoparticles (average size as small as 132.7 nm) was cast using tungsten oxide microparticles as the precursor. Cu/WC nanocomposites can exhibit simultaneously enhanced microhardness, strength, and Young's modulus without significant degradation of the electrical/thermal conductivity. The as-solidified Cu/40 vol.% WC showed a yield strength over 1000 MPa, a Young's modulus over 250 GPa, and still maintained reasonable electrical and thermal conductivity. In addition, a CuAlMg/TiB2 nanocomposite was designed and fabricated by casting. Results showed that TiB2 nanoparticles effectively increased the hardness while causing less deterioration of the electrical conductivity compared to alloying of Al and Mg. Nanoparticle-enabled grain modification was investigated. Bimodal grain structure has been demonstrated effective to overcome the strength-ductility tradeoff in nanostructured materials. We report a new and scalable method to fabricate bimodal grained metals, i.e., casting followed by regular hot rolling, when the metals are loaded with nanoparticles. After hot rolling, as WC nanoparticles restricted grain growth, the nanoparticle-rich zones retained ultrafine grains, while the grains in the nanoparticle-sparse zones grew to microscale. This new pathway has great potential to advance the scalable manufacturing of bimodal grained metals for various applications. In addition, it was discovered that microparticles (CrB and CrB2) with surface nanofeatures can enable ultrafine/nanograined Cu via slow cooling. CrB/CrB2 microparticles, formed by coalescence of nanoparticles in Cu matrix, displayed surface nanofeatures, which induced substantial grain refinement and stabilization down to the ultrafine/nanoscale. The UFG Cu/CrB and Cu/CrB2 samples exhibit exceptional thermal stability, comparable to UFG Cu induced by nanoparticles, without coarsening after annealing at 600 C for 1 h. The nanoparticle enabled phase modification in Cu alloys was studied targeting the intermetallic phase, the solid solution, and the precipitates, which potentially offers a profound impact on alloy design. High-Al bronze (Cu-14Al) has high hardness, wear resistance, but extremely low ductility, resulted from the brittle intermetallic phases especially at the grain boundaries. Nanoparticles tuned the morphology and distribution of the intermetallic phases, effectively increasing ductility. In addition, Cu-4Al is a corrosion-resistant alloy, comprised of Al solid solution in Cu. Dispersed TiB2 nanoparticles not only significantly increased its hardness and modulus, but also mitigated the intergranular corrosion, which is anticipated to arise from the reduced grain boundary energy of serrated grain boundaries in the nanocomposite sample and the partially blocked dealumination by nanoparticles at the grain boundaries. For many alloys, bulky and brittle intermetallic phases are detrimental to their properties, and the refinement of those phases is considered a long-time challenge. Here, we show that nanoparticles can modify and refine such intermetallics to the ultrafine/nanoscale during solidification. Cu-ZrCuSi pseudo-binary alloy was nano-treated by WC nanoparticles. Significant morphology transformation and refinement of ZrCuSi down to the ultrafine/nanoscale was achieved upon the addition of 4 vol.% WC nanoparticles, which arose from the nanoparticle-enabled phase control during solidification. The CuZrSi alloy with 4 vol.% WC nanoparticles exhibit simultaneously enhanced hardness, strength, and plasticity over pure CuZrSi. Cu-Cr alloys are a class of high-strength high-conductivity Cu alloys. However, the strength of Cu-Cr alloys by precipitation-hardening has reached a certain limit. Cu-Cr alloy containing W nanoparticles was fabricated. W nanoparticles accelerated the precipitation, leading to a significant reduction in the peak-aging time. Moreover, the nano-treated sample exhibit increased peak microhardness and improved thermal stability. Thus, nano-treating the Cu-Cr alloys is promising to break the limits of current Cu-Cr alloys. In summary, this dissertation has demonstrated the effectiveness of dispersing nanoparticles into Cu/Cu alloys to achieve high performance Cu. First, nanoparticles with suitable volume fractions can effectively enhance the mechanical properties without significantly deteriorating the electrical/thermal properties of pure Cu. Second, nanoparticles can modify the grain structures of Cu during solidification, enabling bimodal grained and ultrafine grained Cu. Third, nanoparticles can enable Cu alloys with much improved properties by refining intermetallics to ultrafine/nanoscale (CuZrSi alloy), enhancing aging behavior (Cu-Cr alloy), mitigating intergranular corrosion (Cu-4Al), and modifying the morphology and distribution of the brittle phases to improve ductility (Cu-14Al). This approach breaks the limits of traditional liquid metallurgy and lays a foundation for the rational design of high performance metals with dispersed nanoparticles for widespread applications.
