Hot Isostatic Pressing (HIP)

Hot Isostatic Pressing (HIP), is the simultaneous application of heat and high pressure to materials. A HIP unit consists of a high temperature furnace enclosed within a pressure vessel. Work pieces are heated under a uniform, isostatic pressure of inert Argon gas. The result is elimination of internal voids (i.e. porosity) and improved microstructure. HIP is effective with almost all materials – metals, ceramics and plastics. The reduced porosity of HIP’ed materials enables improved mechanical properties such as fatigue strength and increased workability. The HIP process densifies and creates a clean uniform microstructure. Examination of HIPPED parts by non destructive testing techniques show excellent results. These characteristics are not possible with welding or casting. The HIP process can produce materials from metallic compositions that are difficult or impossible to forge or cast.

Applications:

Removal of porosity in castings
Consolidation of encapsulated powders to near-net shape forming
Densification of MMC’s and Ceramics
Advanced diffusion bonding techniques (cladding)

Please contact the TTI Letchworth site for further detail and possibilities with the HIP process.
