In this discussion of hot isostatic pressing (HIP) consideration will be limited to systems and processes which operate above 1000 °C and 1000 kg/cm2. The HIP process came into use in 1957 when Sailer, Hodge, Paprocki, and Dayton, all of the Battelle Memorial Institute, filed a U.S.

Hot Isostatic Press Technology
Powder Metallurgy, 1983AbstractHot isostatic pressing can be considered a rather new form of technology, even though it was first applied in the mid 1950S. During the past 10 years, however, a large increase in the number of applications has occurred. Equipment design has also evolved greatly.

Hot isostatic pressing furnaces
IEEE Control Systems, 2000A robust fault-tolerant model predictive control (MPC) scheme for the precise control of temperature in hot isostatic pressing (HIP) furnaces was designed based on a nonlinear state-space representation of the dynamics of the temperature in an HIP furnace. The model was developed and validated using the data collected from open-loop experiments.

Hot Isostatic Pressing. Heißisostatisches Pressen
Materialwissenschaft und Werkstofftechnik, 1990AbstractHot Isostatic Pressing (HIP) is a technique for producing structural parts under temperatures and pressures in a special sort of a sintering process. HIP is on one hand a forming technique, on the other hand a densifying technique HIP can also be used for diffusion welding especially for metal and ceramic composites.

Hot-isostatic pressing diagrams: New developments
Acta Metallurgica, 1985Abstract The equations and procedures for constructing hot-isostatic pressing diagrams are greatly simplified and clarified. In earlier work, three classes of mechanism were modelled: plastic yielding, power-law creep and diffusional densification. In this paper two further mechanisms are added: the diffusional deformation of the particles themselves

Hot isostatic pressing of beta-alumina
Journal of Materials Science, 1980The effect of hot isostatic pressing on the properties of sintered beta-alumina has been investigated. The mechanical strength is increased as compared with as-sintered material. The ionic resistivity is decreased by hot isostatic pressing but this has been shown to be related to the heat treatment rather than the application of pressure.

Modeling of Hot Isostatic Pressing
2010Abstract This article discusses the two major applications of hot isostatic pressing (HIP), such as healing of inherent internal defects in castings and welds, and consolidation of powder materials. It describes the design principles of the HIP tooling, as well as the problems associated with mathematical modeling of HIP.

Superplasticity of Hot Isostatically Pressed Hydroxyapatite
Journal of the American Ceramic Society, 1990Dense and translucent hydroxyapatite polycrystals (Ca 10 (PO 4 ) 6 (OH) 2 with a grain size of 0.64 μMm) were obtained by hot isostatic pressing at 203 MPa and 1000°C for 2 ...
