B4C-Al Composites Fabricated by the Powder Metallurgy Process
Due to the large thermal neutron absorption cross section of 10B, B4C-Al composites have been used as neutron absorbing materials in nuclear industries, which can offer not only good neutron shielding performance but also excellent mechanical properties. The distribution of B4C particles affects the mechanical performance and efficiency of the thermal neutron absorption of the composite materia...
متن کاملMECHANICAL PROPERTIES OF METAL MATRIX COMPOSITES (Al/SiCp) PARTICLES PRODUCED BY POWDER METALLURGY
Metal matrix composites (MMCs) have become attractive for engineering structural applications due to their excellent specific strength property and are increasingly seen as alternative to the conventional materials particularly in the automotive, aerospace and defence industries. Al/SiC MMC has aluminium matrix and the silicon carbide particles as reinforcements and exhibits many desirable mech...
متن کاملFABRICATION OF Al-SiCp COMPOSITES THROUGH POWDER Metallurgy Process and Testing Of Properties
Metal matrix composites are the class of composite materials finding vast applications in automotive, aircraft, defense, sports and appliance industries. A horizontal ball mill has been fabricated for milling of aluminum and SiC particles. The change in powder particle morphology during mechanical alloying of Aluminum and SiC powders using horizontal ball mill was studied. Al-SiCp composites wi...
متن کاملPorous, Superelastic NiTi Produced by Powder-Metallurgy
Near-stoichiometric NiTi was foamed in the solid state at elevated temperatures through creep expansion of highpressure argon pores previously entrapped during powder consolidation. A sample with 17% porosity was found to be superelastic up to a compressive stress of 800 MPa.
متن کاملMachinable α-SiAlON/BN Composites
Dense machinable α-SiAlON/BN composites were fabricated by hot-pressing using turbostratic boron nitride (tBN) obtained from nitridation of melamine diborate. The tBN was added to the starting powders, or introduced as a coating that formed in situ on α-Si3N4 carrier powders during nitridation, and was subsequently converted to hexagonal boron nitride (hBN) during hot pressing by solution repre...
