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 کاملEffects of Friction Stir Process Parameters on Microstructure and Mechanical properties of Aluminum Powder Metallurgy Parts
The effects of friction stir processing (FSP) on the microstructure and mechanical properties of aluminum powder metallurgy (PM) parts was investigated. PM parts were then subjected to FSP at advancing speeds (v) of 40-200 mm/min and tool rotational speeds (ω) of 800-1600 rpm. Microhardness (HV) and tensile tests at room temperature were used to evaluate the mechanical properties of the frictio...
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 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 کاملLubricant Pyrolysis During Sintering of Powder Metallurgy Compacts
The chemistry surrounding the pyrolysis of N,NЈ-ethylenebisstearimide (EBS) compacted with iron powder is described for the first time. Heat treatment is carried out in a 5 vol pct hydrogen atmosphere (balance nitrogen) over the 100 °C to 850 °C range. The exhaust from the furnace is monitored by Fourier transform infrared and dispersive ultraviolet absorption spectroscopy; condensable material...
