Introduction – Historical background, important steps in powder metallurgy (P/M) process – Advantage and Limitations and Applications. Methods – Production of ceramic powders, automation, rapid solidification technique. Characteristics: sampling – chemical composition, particle shape and size analysis, Surface area, packing and flow characteristics, Porosity and density, compressibility, Strength properties. Blending and mixing of metal powders; Compaction of powders, pressure less and pressure compaction techniques, Hot temperature compaction – Uni-axial hot pressing, Hot extrusion, Spark sintering, Hot isostatic pressing, Injection moulding – Sintering: Types, Theory, process variables, Effects, atmospheres, metallographic technique for sintered products. Post sintering operations; Products: Porous parts, sintered carbides, cermets, dispersion strengthened materials, electrical applications, sintered friction materials. Atomization, Mechanical alloying, Metal Injection moulding, Microwave sintering and self propagating high temperature synthesis.
