Hot Isostatic Pressing

Hot isostatic pressing (HIP) takes various forms:

A solid-state PM process for simultaneously heating and forming a fully dense part either by:
a. Encapsulating powder in an evacuated and hermetically sealed sheet metal canister, or
b. Sintering a pressed or CIPed compact to high enough density to allow unencapsulated HIP to achieve full density. Equal pressure is applied in all directions (isostatic) at a temperature high enough for plastic deformation and sintering to occur to reach theoretical density.
A process that subjects a casting, MIM component, part created by additive manufacturing or powder forging to both elevated temperature and isostatic gas pressure in an autoclave. The most widely used pressurising gas is argon. When these components are HIPed, the simultaneous application of heat andpressure eliminates internal porosity through a combination of plastic deformation, creep and diffusion leading to densification.
A process that allows diffusion bonding to occur to fuse two or more materials, either in solid or powder form, together on an atomic level.
