METALS
Aluminum castings: For void closure to improve properties and to meet
x-ray NDT requirements.
Typically the voids must be under vacuum to allow closure.
Titanium castings: For void and crack closure to increase fatigue ratings
and allow predictable life
cycle determination.
Super Alloys: Parts are produced directly from powder. The benefits
are reduced machining,
improved properties, complex shape capability, and material cleanliness.
Noble Metals: Gold and Platinum can be HIPped to eliminate voids, increase
properties, and to
create compounds and alloys only possible with powder metallurgy.
Refractory Metals: Tungsten, Molybdenum, Niobium, and others all can
be made to near
theoretical densities from powders. HIPping also allows bonding of
similar or dis-similar materials.
Powders: Chrome, Beryllium and others are materials that can be of much
higher purity when
HIPped from powders.
CERAMICS
Oxides: Alumina, Zirconia, and others are routinely HIPped. The density
improvement adds
considerable benefits in toughness and cracking resistance.
Nitrides: Silicon Nitride is among the most promising material for HIPing.
Fatigue and creep
properties are increased. HIPping is one of few methods capable of
SiN4 production.
Carbides: Tungsten Carbide and Silicon Carbide are widely HIPped to
increase fracture resistance.
COMPOSITES
There are numerous composites with both ceramic and metal matrixes
that are being HIPped. The capability to densify and bond dis-similar materials
of widely varying melting temperatures is a unique feature only offered
by high pressure HIPping.
