Paper Title:
Tensile Properties of HIP/DB'ed Ni-Base Superalloys
  Abstract

Hot isostatic pressing(HIP)/diffusion bonding(DB) was employed for cast superalloy MM247 and P/M superalloy Udimet720. The effects of P/M Udimet720 particle size, holding time for HIP/DB and post heat-treatment on the microstructure and tensile properties were investigated. Tensile properties of HIP/DB’ed MM247/Udimet720 were improved at room temperature and 650°C with decreasing powder size from –140mesh to –270mesh, and with increasing HIP/DB time from 2h to 3h. Post-HIP heat-treatments, which strengthen the soft MM247 with cuboidal ’ precipitation, are proposed to enhance the mechanical properties of the HIP/DB’ed MM247/Udimet720.
