Microstructural evolution and dynamic recrystallization mechanism of a heavily-alloyed Ni-based superalloy during hot extrusion
Direct hot forging of heavily-alloyed Ni-based superalloy castings usually ends up with severe cracking due to serious macro-segregation. To address this issue, we propose to use hot extrusion as the replacement technology to process this kind of superalloys. An advanced cast and wrought Ni-based su...
