Powder Consolidation
During hot isostatic processing, metal, ceramic, or composite powders
are consolidated. With the application of pressure and temperature, the
powder is compacted to fully dense parts of various intermediate and finished
products, including billets to be further worked by forging and rolling
from which parts are machined.
ADVANTAGES OF HOT ISOSTATIC PROCESSING
-
Fine structure,
isotropic properties
-
Mechanical
properties equal to or better than wrought counterparts
-
Produce high
quality components out of material otherwise difficult to fabricate
-
Produces smooth
shapes reducing stress concentrations
-
Produces net
or near-net shapes, leading to reduced machining costs
-
Improved fatigue
strength
-
Bonds two
or more materials together with one or all being powder while
producing a seamless interface
