Hot Isostatic Pressing
Arconic Power and Propulsion performs hot isostatic pressing (HIP) services as part of our Specialty Products Group. The HIP process involves the simultaneous application of elevated temperature and isostatic gas pressure to a material for a specified period of time. Using this process, voids within a casting are reduced or eliminated through a combination of creep and diffusion bonding. Primary applications are the reduction of microshrinkage, the consolidation of powder metals, ceramic composites and metal cladding.
In 1976, after an extensive development program initiated in the mid-1960's, Arconic Power and Propulsion became the first company to offer HIP-production services to the aerospace industry. Today the company operates one of the largest HIP facilities in the world.
