This book was released on 2014 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Yttria-stabilized zirconia (YSZ) is of interest as a particle reinforcement in metal matrix composites (MMCs). It possesses high toughness as a result of transformation toughening, along with being an affordable and easily available nanometric powder. Cryomilling was used to produce two batches of aluminum alloy 5083 (AA5083) metal matrix composites incorporating YSZ as the reinforcement, one batch with 2.2 vol.% YSZ (ONR19, MD0, MD0+Ext), and the other with 10 vol.% YSZ (MD1, MD2). For the second batch cryomilling time was reduced from 12 hr to 8 hr, and degassing temperature reduced from 500 °C to 415 °C. Parameters and consolidation methods were varied in the second batch based on lessons learned from the first batch. Chemical reactions between the reinforcement and matrix causing YSZ to decompose and form Al3Zr intermetallics during high temperature processing were studied via differential scanning calorimetry comparison of cryomilled AA5083 with and without YSZ reinforcement. A reaction onset temperature of 420 °C was found when nanometric YSZ was present in the composite. Microstructural characterization of the consolidated materials found YSZ to be well distributed. Grain sizes ranged from a low of 77 ± 41 nm for hot isostatically pressed MD0 material to 362 ± 185 nm for MD0+Ext which had been secondarily processed by extrusion. Mechanical properties were evaluated via tension and compression testing. Ultimate tensile strength (UTS) of 795 MPa with 1.84% strain to failure, and ultimate compressive strength (UCS) of 861 MPa with 10.8+% strain to failure were measured. MD1 material exhibited a 611 MPa UCS with an impressive 22.5% strain to failure. High temperature 400 °C compression test results were exceptional with MD1 retaining 30% of its room temperature strength. Overall, the fabricated materials were found to be sensitive to processing parameters, but strong with good compressive ductility and excellent high temperature strength.

Download or read book Reinforcement Size Effect in Cryomilled Aluminum Boron Carbide Metal Matrix Composites written by Hanry Yang and published by . This book was released on 2015 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The physical and mechanical characteristics of cryomilled Al 5083-boron carbide (Al-B4C) metal matrix composites render them both scientifically interesting and technologically important. Trimodal architectures (containing three components: i) nanocrystalline/ultrafine grains, ii) coarse grains, and iii) ceramic reinforcements) allow for multiple degrees of freedom in the design of the microstructures that can be engineered, for example, to achieve combinations of strength, ductility,and damage resistance that are not attainable with conventional materials. The influence of the nano/ultrafine grains and coarse grains has been extensively studied, but the influence of the reinforcement size and morphology remained relatively unknown. Via cryomilling, which involves mechanical milling in a cryogenic liquid slurry (e.g., nitrogen), and subsequent hot consolidation, novel trimodal composites reinforced with micrometric ([mu]m-), submicron (s[mu]), and nanometric (n-) B4C particles with both faceted and spherical morphologies were fabricated with varying volume fractions of coarse grain phase (0-30%). The microstructural features are investigated in depth, the strengthening mechanisms quantitatively evaluated, and the mechanisms for enhancing strength and/or ductility are discussed. The characteristics of B4C/Al interfaces, namely local chemistry and interfacial structure, were studied in detail and revealed significant differences in these characteristics as a function of particle length scale. n-B4C reinforced composites were observed to have higher strengths, without any loss in deformability, and lower elastic modulus than s[mu]-B4C and [mu]m-B4C reinforced composites due to enhanced damage tolerance and limited load bearing capacity, respectively. Fiber-like arrays of nanoparticle-rich zones containing spherical n-B4C particles embedded in an ultrafine grain Al matrix demonstrated enhanced mechanical response when compared to an equivalent metal matrix composite with a homogeneous distribution of nanoparticles.

This book was released on 2004-06-29 with total page 451 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the fall of 1998, Prof. Sergey Firstov invited me to the Frantcevych Institute for Problems of Materials Science (IPMS) in Kyiv, Ukraine to discuss possible collaborations in the area of advanced metals research. During this visit, a strong mutual interest was evident in a broad range of structural metals technologies, and a quick friendship was established. Countless subsequent emails and a reciprocal visit to the U. S Air Force Research Laboratory by Prof. Firstov and a team of scientists from IPMS ensued to discuss and detail a broad collaboration in the area of structural metals. Two years after the initial visit, a major investment by the U. S. Air Force Office of Scientific Research (AFOSR) was established to pursue the technologies defined by these interactions. The annual reviews of the AFOSR Ukrainian Metals Initiative were held in late May, a most beautiful time in Kyiv when the lilacs are in bright display and the air is scented with the smell of falling blossoms from the chestnut trees that line the major streets and many parks. The sunny days and mild evenings provide a welcome break from winter, and on weekend evenings festive crowds spill onto the Khreshchatyk, Kyiv’s downtown boulevard, to listen to street musicians, watch jugglers and comedians, or simply to celebrate with friends. The annual reviews featured long days of intensive discussion of technical progress, followed in the evenings by the warm hospitality of the Ukrainian hosts.

Download or read book Superplasticity in Metals and Ceramics written by T. G. Nieh and published by Cambridge University Press. This book was released on 1997-01-23 with total page 288 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes advances in the field of superplasticity, the ability of certain materials to undergo very large tensile strains. This phenomenon has increasing commercial applications, but also presents a fascinating scientific challenge in attempts to understand the physical mechanisms that underpin it. The authors emphasize the materials aspects of superplasticity. Beginning with a brief history of the phenomenon, they describe the two major types of superplasticity-- fine-structure and internal-stress superplasticity-- and discuss their operative mechanisms. They also present microstructural factors controlling the ductility and fracture in superplastic materials. Observations of superplasticity in metals (including aluminum, magnesium, iron, titanium and nickel), ceramics (including monoliths and composites), intermetallics (including iron, nickel, and titanium base), and laminates are thoroughly described. This is a valuable text for graduate students and researchers in materials science and engineering.

Download or read book Field Assisted Sintering written by Eugene A. Olevsky and published by Springer. This book was released on 2018-08-09 with total page 432 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book represents the first ever scientific monograph including an in-depth analysis of all major field-assisted sintering techniques. Until now, the electromagnetic field-assisted technologies of materials processing were lacking a systematic and generalized description in one fundamental publication; this work promotes the development of generalized concepts and of comparative analyses in this emerging area of materials fabrication. This book describes modern technologies for the powder processing-based fabrication of advanced materials. New approaches for the development of well-tailored and stable structures are thoroughly discussed. Since the potential of traditional thermo-mechanical methods of material treatment is limited due to inadequate control during processing, the book addresses ways to more accurately control the resultant material's structure and properties by an assisting application of electro-magnetic fields. The book describes resistance sintering, high-voltage consolidation, sintering by low-voltage electric pulses (including spark plasma sintering), flash sintering, microwave sintering, induction heating sintering, magnetic pulse compaction and other field-assisted sintering techniques. Includes an in-depth analysis of all major field-assisted sintering techniques; Explains new techniques and approaches for material treatment; Provides detailed descriptions of spark plasma sintering, microwave sintering, high-voltage consolidation, magnetic pulse compaction, and various other approaches when field-assisted treatment is applied.
