Deformation behaviors of non-metallic inclusion in FGH96 superalloy during different plastic processes Mincong Zhang 1,a, Chenyi Liu 1,b and Shuyun Wang1,c 1Beijing Institute of Aeronautical Materials, Beijing 100095, China amincong-zh@163.com, bliuchenyi534574@sohu.com, cshuyun.wang@biam.ac.cn Keywords: FGH96 superalloy; non-metallic inclusions; isothermal forging; hot extrusion; deformation behavior Abstract.
Introduction Powder metallurgy (PM) nickel-base superalloy is introduced and developed as turbine disk material in order to solve solidification segregation and processing difficult caused by high-alloy wrought nickel-base superalloy.
But PM nickel-base superalloy is a material sensitive to notch and is influenced by defects easily.
