Powder Metallurgy

Powder Metallurgy is a technology which exhibits economy in the use of raw materials and energy, combined with attractive properties of the products. Only the name appears more restrictive than what the technology is capable of; for, powder metallurgy techniques are equally applicable to non-metals. The advantages of powder metallurgy are particularly evident in the areas where material and processing costs are high, or conventional routes for materials processing are difficult to follow.;The Soviet Union is renowned for its extensive and innovative application of the science and technology of powder metallurgy; India has a growing base in powder metallurgy related industries, research and development, and also has several experts in the field. This book symbolizes the long years of scientific collaboration, professional contacts between these two countries, and is the culmination of editorial efforts of two senior and experts in powder metallurgy.;This volume discusses the current issues on the application on powder metallurgy techniques to material processing. In recent years there have been significant developments in areas of interest to powder metallurgy. One is concerned with powder-making where the usual limitations of alloying among elements have been overcome. Rapidly solidified powders are not only fine-grained or even amorphous, but enlarge the alloying ranges as well. Mechanical alloying enables the incorporation of non-metallic dispersoids uniformly in powder. Powders are also becoming purer, free in inclusions, ensuring better mechanical properties after processing. These are welcome, specially in areas where load-bearing applications are envisaged.
