Hot deformation behavior of hard-to-deform Ni-based Alloy
Journal of Physics: Conference Series, 2021 Abstract The very poor hot workability of hard-to-deform GH4742 alloy is represented in the aspects of very narrow available deformation temperature range, high deformation-resistant force and low thermoplasticity. In this paper, the hot deformation behavior of a Ni-based superalloy was studied in the temperature range of 1060-1160°C and
