In this paper, the results of a recent study designed to improve our understanding of the hardness, tensile properties, cyclic fatigue response, and fracture characteristics of a spray-atomized and deposition-processed Al-Cu-Mg-Ag Alloy are presented. Specimens of the alloy were deformed to failure at ambient temperature under both quasi-static and cyclic stress amplitude-controlled conditions. Th...... hiện toàn bộ

Synthesis and Characterization of a Free-Standing, One-Dimensional, Al-Cu/SiC-Based Functionally Graded MaterialJournal of Materials Synthesis and Processing - Tập 10 - Trang 75-81 - 2002
M. Gupta, M. O. Lai, T. S. Srivatsan
In this research paper the synthesis of aluminum-copper/silicon carbide–based (Al-Cu/SiC) functionally gradient material using the innovative technique of gradient slurry disintegration and deposition is presented and discussed. Using the gradient slurry disintegration and deposition technique a gradient of SiC was established using an initial weight percentage of 15%. Results of the synthesis wer...... hiện toàn bộ
Interfacial Microstructure and Reaction Phases of Solid State Bonded at SiC/V JointsJournal of Materials Synthesis and Processing - Tập 6 - Trang 387-392 - 1998

SiC was bonded to SiC using V foil at temperatures ranging from 1473 K to 1673 K for 1.8 to 64.8 × 103 s and 30 MPa in vacuum. Interfacial reactions and microstructures were investigated using electron probe microanalyser and X-ray diffractometer. SiC begins to react with V at temperatures above 1473 K. Granular V2C phase was formed at the V side of the reaction zone, while a layer of V3Si phase w...... hiện toàn bộ

Dispersion and Rheological Properties of Alumina/Zirconia Slurries with Methyl Isobutyl Ketone/Ethanol SolventsJournal of Materials Synthesis and Processing - Tập 10 - Trang 237-244 - 2002
H. C. Park, S. Y. Yoon, Y. B. Lee, B. K. Kim, R. Stevens
The dispersion and rheological behavior of alumina, zirconia, and alumina/zirconia mixed slurries were investigated using various solvent ratios of methyl isobutyl ketone (MIBK)/ethanol (EtOH), by measuring sedimentation bulk density, particle size distribution, and viscosity. Well-dispersed suspensions were obtained in MIBK-rich solvents with additional dispersant and in EtOH-rich without dispers...... hiện toàn bộ

of reactions, the reaction mechanism of combustion synthesis of AlN is possibly the reactions between N2 and Al vapor and/or liquid Al. Other oxides of Al, such as Al2O, AlO, can also react with N2 to form AlN. However, the reaction between liquid Al and N2 as well as the reactions b...... hiện toàn bộ
Study of a Pure-Ge/Si Short-Period Superlattice by X-Ray Double Crystal DiffractionJournal of Materials Synthesis and Processing - Tập 7 - Trang 205-207 - 1999

Pure-Ge/Si short-period superlattice (SPS) samples consisting of 1.5-monolayer Ge and a 1.4- to 3.8-nm-thick Si layer grown by gas source molecular beam epitaxy (GS-MBE) were studied by double-crystal x-ray diffraction. For SPS with a Si layer less than 2.4 nm, the satellite peak caused by the SPS structure in the rocking curve is quite broad, and no fine structure is found, indicating that there ...... hiện toàn bộ
Optimization of PVD Parameters for the Deposition of Ultrahard Ti–Si–B–N CoatingsJournal of Materials Synthesis and Processing - Tập 7 - Trang 187-193 - 1999

Multicomponent Ti–Si–B–N coatings were deposited on high-speed steel (HSS) substrates by reactive magnetron sputtering using a SHS TiB + 20 wt% Si target. The influences of the substrate temperature, bias voltage, and nitrogen partial pressure on the structure and the elemental compositions of the films were studied. The films were characterized by high-resolution transmission electron microscopy ...... hiện toàn bộ
