This book was released on 2005 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: Synthesis/processing of nanostructured (amorphous or ultra fine grained) materials was studied via various processing routes such as gas atomization, melt spinning, cryomilling, equal-channel angular pressing (ECAP) and conventional consolidation. Microstructures and mechanical properties of both the amorphous powders and consolidated bulk materials were characterized. The amorphous alloy of A185Ni10La5 (at.%) was fabricated in terms of melt-spun ribbons and particularly, gas-atomized powders (25 micrometers). The kinetics and microstructure evolution during the devitrification process were carefully investigated using DSC, XRD. SEM, TEM, and SAxS. It was found that quenched-in fcc-Al nuclei present in amorphous Al85Ni10La5 powders. Annealing at 235 degrees C leads to growth of the quenched-in nuclei with the grain size stabilized around 10 nm. With increasing annealing temperatures (i.e., at 245 degs C, 250 degs C and 263 degs), the devitrification takes place via eutectic crystallization with a resultant grain size around 20 nm. At the temperatures283 degs, the devitrification tends to complete in a short time ( -5 min), however, this alloy shows excellent thermal stability to resist grain growth. The influence of devitrification, under various annealing temperatures, on mechanical response was studied by nanoindentation technique. Bulk nanostructured materials were synthesized by consolidating the amorphous Al85Ni10La5 alloy powder with 5083 Al alloy powder milled under cryogenic temperature (cryomilling). The addition of cryomilled 5083 Al alloy is to further increase the specific strength for the bulk materials (e.g.,>1000 MPa in compression with the density -2.9 g/cc). The bulk nanostructured material also shows high strength at elevated temperatures (i.e., 400 MPa in compression at 200deg). At room temperature the tensile properties were found be lower than the compressive properties and this differential effects should be investigated in the future st7.

This book was released on 2015-02-24 with total page 117 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents cutting-edge research on the design and development of novel, advanced high-strength, light-weight materials via the incorporation of novel reinforcements, namely, metallic amorphous alloys/bulk metallic glasses (BMG), in light metal matrix composites (LMMCs) based on Al and Mg. The book begins with an introduction to conventional ceramic reinforced light metal matrix composites, along with the major drawbacks which limit their application. Metallic amorphous alloys/Bulk Metallic Glasses (BMG) are new class of metallic materials that are distinctly differently from conventional metals/alloys in terms of their structure and thermal behavior, and exhibit extremely high strength (1 to 2 GPa) and large elastic strain limit (1 to 2%). Given these unique properties, upon their incorporation into Al/Mg-matrices, they provide superior interfacial properties, i.e. high degree of compatibility with the matrix due to their metallic nature when compared to conventional ceramic reinforcements, and thereby significantly enhance the mechanical performance of LMMCs. Amorphous/BMG reinforced LMMCs is an emerging research field and the existing literature is meager. This book discusses the various processing methods that would be suitable for these novel materials. A comparison of mechanical properties and strengthening mechanisms of amorphous/BMG reinforced composites with those of conventional ceramic composites is presented. Future research directions and wider research potential of the novel materials are discussed, and prospective applications are highlighted. For ease of understanding and comparison, appropriate schematics, tables, and figures are provided.

Available in PDF, EPUB and Kindle. Book excerpt: The Special Issue “Synthesis and Modification of Nanostructured Thin Films” highlights the recent progress in thin film synthesis/modification and characterization. New methods are reviewed for the synthesis and/or modification of thin films based on laser, magnetron, chemical, and other techniques. The obtained thin nanostructures are characterized by complex and complementary techniques. We think that most of proposed methods can be directly applied in production, but some others still need further elaboration for long-term prospective applications in lasers, optics, materials, electronics, informatics, telecommunications, biology, medicine, and probably many other domains. The Guest Editor and the MDPI staff are therefore pleased to offer this Special Issue to interested readers, including graduate and PhD students as well as postdoctoral researchers, but also to the entire community interested in the field of nanomaterials. We share the conviction that this can serve as a useful tool for updating the literature, but also to aid in the conception of new production and/or research programs. There is plenty of room for further dedicated R&D advances based on new instruments and materials under development.

Available in PDF, EPUB and Kindle. Book excerpt: This is the second volume of an advanced textbook on microstructure and properties of materials. (The first volume is on aluminum alloys, nickel-based superalloys, metal matrix composites, polymer matrix composites, ceramics matrix composites, inorganic glasses, superconducting materials and magnetic materials). It covers titanium alloys, titanium aluminides, iron aluminides, iron and steels, iron-based bulk amorphous alloys and nanocrystalline materials.There are many elementary materials science textbooks, but one can find very few advanced texts suitable for graduate school courses. The contributors to this volume are experts in the subject, and hence, together with the first volume, it is a good text for graduate microstructure courses. It is a rich source of design ideas and applications, and will provide a good understanding of how microstructure affects the properties of materials.Chapter 1, on titanium alloys, covers production, thermomechanical processing, microstructure, mechanical properties and applications. Chapter 2, on titanium aluminides, discusses phase stability, bulk and defect properties, deformation mechanisms of single phase materials and polysynthetically twinned crystals, and interfacial structures and energies between phases of different compositions. Chapter 3, on iron aluminides, reviews the physical and mechanical metallurgy of Fe3Al and FeAl, the two important structural intermetallics. Chapter 4, on iron and steels, presents methodology, microstructure at various levels, strength, ductility and strengthening, toughness and toughening, environmental cracking and design against fracture for many different kinds of steels. Chapter 5, on bulk amorphous alloys, covers the critical cooling rate and the effect of composition on glass formation and the accompanying mechanical and magnetic properties of the glasses. Chapter 6, on nanocrystalline materials, describes the preparation from vapor, liquid and solid states, microstructure including grain boundaries and their junctions, stability with respect to grain growth, particulate consolidation while maintaining the nanoscale microstructure, physical, chemical, mechanical, electric, magnetic and optical properties and applications in cutting tools, superplasticity, coatings, transformers, magnetic recordings, catalysis and hydrogen storage.

Available in PDF, EPUB and Kindle. Book excerpt: As nanotechnology has developed over the last two decades, some nanostructures, such as nanotubes, nanowires, and nanoparticles, have become very popular. However, recent research has led to the discovery of other, less-common nanoforms, which often serve as building blocks for more complex structures. In an effort to organize the field, the Handbook of Less-Common Nanostructures presents an informal classification based mainly on the less-common nanostructures. A small nanotechnological encyclopedia, this book: Describes a range of little-known nanostructures Offers a unifying vision of the synthesis of nanostructures and the generalization of rare nanoforms Includes a CD-ROM with color versions of more than 100 nanostructures Explores the fabrication of rare nanostructures, including modern physical, chemical, and biological synthesis techniques The Handbook of Less-Common Nanostructures discusses a classification system not directly related to the dimensionality and chemical composition of nanostructure-forming compounds or composite. Instead, it is based mainly on the less-common nanostructures. Possessing unusual shapes and high surface areas, these structures are potentially very useful for catalytic, medical, electronic, and many other applications.
