Limitations of hot isostatic pressing
NettetSome limitations of uniaxial pressing that concern regular particle packing can be overcome by isostatic pressing (i.e. by applying pressure from all directions). In … NettetHot isostatic pressing (HIP, Fig. "Hot isostatic press device") can be applied as a regeneration procedure for creep deteriorated hot parts.With it inner flaws like creep voids and micro cracks can be compressed and fused with a high outer gas pressure and at hitgh temperatures (Fig. "HIP process limits"). The process is also applied at new parts …

Hot isostatic pressing (HIPing) is a process that can be applied as a post-casting treatment to reduce porosity in castings (Roberts, 2001 ). The process takes components up to a temperature of ∼80% of the absolute melting point, under pressures from 100 MPa to 210 MPa, for up to 6 h.
