P/M industry standards

Abstract

The Center for Powder Metallurgy Technology (CPMT) and Concurrent Technologies Corporation (formerly Metalworking Technology, Inc.), in a cooperative effort, are developing material property data that will be used to establish new P/M standard material property data. Under the first phase of this program, six new material systems will be investigated: air hardening steel, diffusion alloyed steel, prealloyed molybdenum-manganese steel, powder forged alloys, and the effects of manganese sulfide additions on several P/M steels. These alloys will be characterized using property tests outlined in MPIF Standard 35. In the second phase of the program, new physical and mechanical property data for these alloys as well as the current alloys in MPIF Standard 35 will be developed: wear, fatigue, surface endurance limit, machinability, thermal expansion, shear/torsion, fracture toughness, hardenability, and corrosion resistance. Progress on these activities will be reported.
