| (54) | Low porosity powder metallurgy produced components |
| (57) Components produced by powder metallurgy techniques are described herein. Embodiments
of these components have little or no porosity therein after processing. Embodiments
of these components are created by creating a preform from a powder; creating a component
from the preform; heat treating the component to create a predetermined microstructure
therein; and then hot isostatic pressing the heat treated component to reduce any
porosity therein. The components can then be machined to their final dimensions, if
necessary.
