Technology of Hiping Complex Shape Parts with Dual Chemical Composition and properties from Metal Powders: Trends of its Development in the USSR

Abstract

Recently the need for powder parts operating at high temperatures, stresses and in agressive media has grown greately. Complex shape parts with dual chemical composition and properties made with the help of HIP method can fully meet the operation requirements. The main trends of developing such technology in the USSR are:

• production of high strength powder parts by HIP method without consequent plastic deformation;

• using high quality powders;

• production of parts with variable cross-sectional properties meeting the operational requirements;

• introduction of aerospace technologies into national economy.
