Mechanical Alloying and Milling

Abstract

The search for new and advanced materials is the major preoccupation of metallurgists, ceramicists, and material scientists for the past several centuries. Significant improvements in mechanical, chemical, and physical properties have been achieved by alloying and through chemical modification and by subjection the materials to conventional thermal, mechanical, and thermo mechanical processing methods. Present paper deals with a brief review of the mechanical alloying questions focusing on the possible processes and apparatuses (mills). BASIS OF NONEQUILIBRIUM PROCESSING The central underlying them to synthesize material in a nonequilibrium state is to "energize and quench" as proposed by Turnbull [2]. Processes such us as solidstate quenching, rapid solidification from the melt, irradiation, and condensation
