Powder metallurgy methods for producing components

摘要

The manufacture of large, complex components will be extremely costly for the power industry over the next few decades as many of these will be produced from expensive, high strength alloy castings and forgings. EPRI is investigating the use of an alternative manufacturing method, powder metallurgy and hot isostatic processing to produce high quality and potentially less expensive components for power generation applications. Benefits of the process include manufacture of components to near-net shapes, precise chemistry control, a homogeneous microstructure, increased material utilization, good weldability, and improved inspectability.
