Powder
metallurgy is a technique for fabricating parts to near net shape by sintering
metal powders to produce a dense solid. The powders may be of a pure metal,
or may be a controlled mixture of different metals that will form alloys
during the diffusion controlled sintering reaction. In a well designed
process, 97% of the starting raw material will end up in the finished part.
The diagram shows the step sequence involved in this process, including
a hot forming step that is often used for high performance components. |
