METHOD OF MANUFACTURING A COMPONENT BY HOT ISOSTATIC PRESSING

摘要

In a method for manufacturing a homogenous near net-shape component made of a material selected from a metal, a metal alloy, or a metal matrix composite, with the proviso that said the material does not decompose or otherwise undergo a quick chemical reaction before or during it melts or before or during the metal or metal alloy in the metal matrix composite melts, a gas tight container having one or more cavities and one or more walls is formed of said material by additive layer manufacturing (ALM) such that the container contains said material in comminuted form, whereafter the container and its content consisting of the same material is subjected to hot isostatic pressing. A system based on electron beam ALM consisting of a gas tight container without any welding seem and a communited material of the same kind from which the container is formed in the cavity or cavities thereof is also disclosed.
