Powder Metallurgy & its Application to Non-Ferrous Metals

Abstract

The paper introduces the subject of powder metallurgy based on the studies of bond which exists between two atomically smooth surfaces when brought close together. After dealing with the theoretical principles and practical results of sintering homogeneous as well as heterogeneous powders,the applications of powder metallurgical technique to non-ferrous metals and alloys are discussed at length. -Recent notable developments in powder metallurgy, in the field of heat-resistant metallic compositions, essentially of non-ferrous compositions, are dealt along with other developments such as the modern liquid disintegrator method for making metals and alloys into powder and infiltration technique. The paper deals with cermets and latest carbide compositions. The paper concludes with a reference to the possibilities of applying powder metallurgical techniques to Indian nonferrous industries.
