RISDetermination of optimum condition for producing Al/Ni3Al composite powder using blending and mechanical milling
Abstract
Metal matrix composites produced by Ni3Al intermetallic particles dispersed in a ductile aluminum matrix, with outstanding properties, are increasingly used in aerospace and structural applications. In ...
Synthesis and structure of PMN–PT ceramic nanopowder free from pyrochlore phase
Single-phase perovskite 0.65PMN–0.35PT nanopowders were synthesized at low temperature by the auto-combustion method. PMN–PT powder with 1 mol% of excess Pb(NO3)2 was prepared from the constituent nitrates and alkoxide ...
Effects of annealing temperature on some structural and optical properties of ZnO nanoparticles prepared by a modified sol–gel combustion method
Abstract
Plate-shaped zinc oxide nanoparticles (ZnO-NPs) were successfully synthesized by a modified sol–gel combustion method. Zinc acetate, pure
water and isopropanol were used as the starting materials. ...
First-principles study of structural, dynamical, and dielectric properties of A-La2O3
Abstract
We have investigated the structural, dynamical, and dielectric properties of A-La2O3, within density-functional theory. The relaxed structural parameters are found to be in very good agreement with experimental ...
