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

Hot Deformation Behavior of Superalloy 718
Superalloys 718, 625, 706 and Various Derivatives (1994), 1994 ABSTRACT The hot deformation behavior of Alloy 718 was characterized on the basis of the dynamic materials model and compression data in the temperature range of 900 to 1177°C and strain rate range of 0.005 to 5s’. The flow curves at all temperatures and strain rates showed little dependence on strains larger than 0.3.

Characterization of Hot Deformation Behavior in a 13% Chromium Steel
Materials Science Forum, 2018 The behavior of a 13% chromium steel subjected to hot deformation has been studied by performing hot compression tests in the temperature range of 850 to 12000C and at strain rates from 0.01 to 10 s-1. The uniaxial hot compression tests were performed on a Gleeble thermo-mechanical simulator. The best function that fits the peak stress for the material
