Abstract

1. A process for producing metallic materials by the isostatic pressing of metal powders with high contents of gases which are introduced into the metal powder by acting on the metal powder with pressurized reaction gas at elevated temperature, characterized in that : a) after being filled in known manner into a capsule the metal powder is acted upon with the reaction gas, while b) at the same time a process acts on the capsule with the supply of heat from outside under pressure, and c) at the same time as the pressure of the process gas is increased the pressure of the reaction gas is increased approximately identically, d) the pressure being increased until a quantity of reaction gas is enclosed in the volume between the grains of metal powder which is adequate to achieve the required alloying content under the temperature conditions prevailing therein, and then e) the further supply of reaction gas is terminated and f) the pressure of the process gas outside the capsule and the temperature are brought to a value necessary for the isostatic hot pressing.
