When components are treated with the Hot Isostatic Pressing (HIP) process - simultaneous application of elevated heat and pressure with an inert gas atmosphere - internal cavities and micro-porosities are eliminated through a combination of plastic deformation, flow and diffusion bonding of the material.
The HIP process is used to improve a wide range of products, including castings, additively manufactured parts, near net shape parts, ceramics, powder metallurgy, sintered and metal injection moulded parts.
