Development of Mechanical Properties of Ni-based Superalloy for Land-based Gas Turbine
초록
A Study has been made to investigate the effects of hot isostatic press(HIP) and post-HIP heat treatment on microstructures and mechanical properties of Ni-based single crystal superalloy CMSX-4. HIP process was found to heal and close micropores significantly, but did not affect the morphologies of. The elimination of as-cast micropores obtained by HIP process resulted in improved stress-rupture lives of Ni-base single crystal superalloy by 185%.
