The Importance of Powder Metallurgical Techniques and Solid-State Reactions in the Treatment of Metallurgical Problems

  • F. Benesovsky

Abstract

Powder metallurgy has always played a decisive part in the production of refractory metals and cemented carbides. The scientific bases for the pressing and sintering procedures were, however, worked out only in the period between the two world wars. Powder metallurgical methods were not systematically applied in fundamental research until after the Second World War. The advantages of the sintering method over the modern melting methods in alloy-constitution research are discussed, and examples of the work performed at the research laboratory of Metallwerk Plansee A.G. are given. These concern investigations of the binary and multiple systems of the refractory transition metals, the lanthanides, and actinides with silicon, carbon, nitrogen, and boron. The discovery of large groups of ternary intermetallic phases was made possible only by the application of special procedures involving solid-state reactions.

The results of this basic research are already being utilized and powder metallurgical methods applied on a large scale in the production of fuels for gas-cooled, high-temperature power reactors.
