Microstructure evolution and underlying mechanisms during the hot deformation of as-homogenized Ni-Co-Cr superalloys with millimeter-grade coarse grains

The as-homogenized microstructure, characterized by millimeter-grade coarse grains, should be refined during the cogging process to enhance the mechanical properties. In this work, an as-homogenized Ni-Co-Cr superalloy was hot-mechanically processed under conditions of 1150 °C/0.1s−1 with varying st...
