Design in Powder Metallurgy and Sinterforging 710531
The powder metallurgy process for parts fabrication, as well as the sinterforge process, starts with the uniaxial compaction of metal powder in closed dies, thus imparting shape and initiating properties development. Sintering subsequent to compaction further develops properties, and may be followed by coining, resintering, or in the case of sinterforging, by hot compaction. Heat treatment may be applied to either product.
The design procedure discussed in this paper develops a plan with the objective of achieving a three way balance between part function, fabrication, and cost. The stages of the procedure include: analysis of process characteristics, development of process capability, dimensioning, developing specifications, and developing cost feasibility.
