摘要:

Hot isostatic pressing (HIPping) is now becoming a more widely accepted technique for many aspects of materials processing. Two of the most important applications are for the consolidation of powders to near-net-shape and the removal of internal defects such as porosity in castings or creep cavities in high temperature components. The application of HIPping to these two areas is reviewed with particular attention given to the development of predictive models for the consolidation processes.

摘要:

This paper is concerned with the optimization of the solid state diffusion bonding parameters between a nickel-base superalloy (IN 600) and a silica-containing alumina. Shear tests established the relationships between interfacial reactivity, surface roughness, residual thermal stresses and mechanical properties. The effect of cooling rate (from the bonding temperature) was considered through a limited number of experiments (compared to those investigating the influence of time and temperature of HIP bonding). The influence of bonding temperature and of cooling rates on mechanical properties can be interpreted in terms of residual stresses. These stresses also depend on the geometry of assemblies. The physico-chemical aspects at the interface were studied through the influence of time and chemistry.

摘要:

Conditions for hot isostatic processing (HIP) differ widely from conventional processing, particularly in pressure and atmosphere. Sintering dynamics and thermodynamics in this environment are compared to those in more conventional processes such as hot pressing and normal sintering. It is shown that there are situations in which only HIP can produce certain materials. Intermetallics and nitride ceramics sintered by HIP and capsule HIP, as well as superconductor ceramics processed by oxygen HIP, are reviewed.

摘要:

Hot isostatic pressing (HIP) is a well established tool in the areas of powder metallurgy and the healing of castings, the use of which is being continually extended into an increasing range of materials processing. A good example of this new technology is the densification of carbon-carbon composites. The general principles, advantages and disadvantages of HIP fabricated carbon-carbon are described along with novel polyaromatic engineering thermoplastic polymer precursors.

摘要:

The combined role of coating technology and hot isostatic pressing (HIP) is considered in terms of component manufacture and material development. The potential benefits provided by surface and interface engineering followed by consolidation by HIP are highlighted and examples are given for applications such as near-net-shape PM processing, the design and manufacture of metal matrix composites, diffusion bonding and wear/corrosion resistant surfacing.
