This book was released on 1995 with total page 80 pages. Available in PDF, EPUB and Kindle. Book excerpt: This work includes a comprehensive analysis of the effect of thermomechanical processing (TMP) history on the microstructure and properties of 10 and 20 volume percent 6061 Al-Al2O3 discontinuous metal matrix composites (MMCs). Materials in which cold drawing operations were included in the TMP demonstrated increased ductilities for a given strength level when compared to samples which were processed by hot extrusion only. Microstructural analysis provided clear evidence of the absence of damage to reinforcing particles during TMP and of load transfer to these particles during subsequent straining. Failure during tension testing resulted from the ductile tearing of the matrix as voids initiated by the cracking of reinforcement particles, joined together. A distinct microstructural difference related to processing history was the development of a strongly fibered particle distribution in materials experiencing low temperature drawing operations. In order to conduct an analysis of the mechanisms by which the particles are redistributed and reoriented during processing, a channel compression die was constructed which allowed processing to be simulated by compressive straining on a mechanical testing machine. This allowed careful control of the processing parameters. An analysis of the effects of processing temperature on particle redistribution and reorientation was conducted.

This book was released on 1992 with total page 64 pages. Available in PDF, EPUB and Kindle. Book excerpt: The effects of thermomechanical processing parameters on the elevated temperature behavior of a 6061 aluminum -- aluminum oxides metal-matrix composite (MMC) have been studied. The same processing parameters were employed with unreinforced 6061 AL to provide a comparison. These materials were both thermomechanically processed at either 350 C or 500 C using two rolling schedules. Both schedules involved a constant strain per pass. Subsequent mechanical tests were conducted at temperatures 200 to 500 C and strain rates ranging from (6.7E-3)/s to (1.3E-1)/s. The materials processed at 500 C exhibited higher strength when compared to those processed at 350 C for deformation temperatures below 350 c. Materials stabilized by annealing after completion of rolling displayed higher ductilities when compared to the as-processed materials, especially at lower testing temperatures. The peak ductilities of the MMCS occurred at testing temperatures near the prior rolling temperatures. Solution treatment prior to rolling and additional strains during rolling in excess of 2.5 appeared to have no effect on strength or ductility.

Download or read book The Effect of Thermomechanical Processing on Mechanical Properties of a Cast 6061 Aluminum Metal Matrix Composite written by Werner Fletcher Hoyt and published by . This book was released on 1993 with total page 79 pages. Available in PDF, EPUB and Kindle. Book excerpt: Thermomechanical processing was conducted on cast 6061 Al-A12O3 metal matrix composites (MMCs) containing either 10 or 20 volume percent of alumina (A1203) particles. These materials were provided by DURALCAN-USA, Inc., of San Diego, CA in conjunction with a Cooperative Research and Development Agreement (CRDA) program on ductility enhancement for these MMCS. Processing included isothermal forging and rolling of materials at 500 deg C, with interpass anneal (IPA) times of 5 or 30 minutes. Isothermal rolling was also accomplished on 1.0 inch thick 6061-T6 Al plate. Processed materials were solution heat treated at temperatures ranging from 480-560 deg C, and were then age hardened at 160 deg C. Tensile testing was conducted to evaluate strength and ductility. Homogeneity of the particle distribution was improved by processing for both composites and no microstructural damage was apparent. Lower solution heat treatment temperature provided significant ductility enhancement while the longer IPA time at 500 deg C had a minor beneficial effect. As the percentage of reinforcement increased, aging time to peak strength decreased; peak strength, and yield strength increased; and ductility decreased. As the solution heat treatment temperature was decreased ductility was enhanced at a cost of peak strength.

Download or read book The Effect of Thermomechanical Processing Parameters on the Ambient Behavior of 10% Volume 6061 AL-Alumina written by and published by . This book was released on 1992 with total page 88 pages. Available in PDF, EPUB and Kindle. Book excerpt: Thermomechanical Processing was conducted on a 10 vol. pct. 6061 Alumina particle reinforced 'metal matrix composite' (MMC). The TMP employed consisted of isothermal rolling with intermediate annealing, using a schedule of reduction with constrain strain per pass. The as-processed material exhibited high strength while simultaneously achieving ductility comparable to that of the unreinforced 6061 matrix alloy. In the fully annealed condition, the composite's strength and ductility were essentially equal to those of the unreinforced aluminum. An aging study showed accelerated aging and greater peak strength for the composite. Finally, a process and heat treatment combination was established in an attempt to optimize simultaneously the strength and ductility of the composite. It was found that the composite could be aged to a peak strength of 340 MPA while retaining a ductility of 14 percent elongation to failure.

Schaefer and published by . This book was released on 1990 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Thermomechanical processing was conducted on a cast aluminum-based metal matrix composite. The material studied was 6061 aluminum containing 10 volume percent of alumina (Al2O3) particles, fabricated by casting and subsequently extruded by DURALCAN, Inc. Processing included isothermal rolling of an extruded bar to large strain values. As a result of rolling at 500 C, strength was increased, but with a substantial loss of ductility. Further strengthening was realized by rolling at 350 C and no further ductility loss was seen. Homogeneity of the particle dispersion was considerably improved with no evidence of microstructural damage. Upon subsequent solution heat treatment, ductility of the rolled materials was restored to values greater than obtained in material experiencing only extrusion. Also, the strength of the rolled material exceeded that of material heat treated after extrusion. Upon subsequent aging treatment (aging at 160 C), the increased strength and ductility enhancement persisted.

Book excerpt: This book is focused on composites involving powders as the starting materials. It provides relevant information for questions related to the selection of constituent phases, most economic fabrication routes, proper testing procedures, and product optimization. The field is sufficiently advanced that predictive models guide many decisions. Applications are illustrated over a broad range of material and property combinations. This title includes: •Selection of phases with consideration of intersolubility & interface •Microstructure, especially the role of phase connectivity •Fabrication approaches, especially net-shape consolidation •Assessment of typical properties, testing techniques & industry standards •Design & trade-off decisions involved in optimization, including cost •Applications, both those that have matured and some emerging prospects. The reader may have little appreciation for how particulate composites are literally everywhere. Examples include new wear resistant consumer products(Apple watch), longer lasting automotive tires with reduced rolling resistance(Yokohama tires), and new diamond heat sinks for computers(Element Six substrates). Particulate composites also form critical components in applications such as magnets, dental fillings, brakes, darts, bio-implants, & cutting tools. Particulate composites are a multi-billion dollar industry, and can be a cost-effective solution ripe for innovation and continued rapid growth. For the engineer, the wide range of particulate composite formulation and property combinations offers the ability to design for a variety of application and provides ample opportunity for innovation. Particulate Composites: Fundamentals & Applications is ideal for use in a one-semester eng. course at the senior UG/graduate level, and is also suitable as a practical reference for materials scientists in academia and industry.
