Microstructure evolution and flow stress modeling of SA508Gr.4N steel during hot deformation process
The isothermal deformation behavior of Ni-Cr-Mo low alloy SA508Gr.4N steel at deformation temperature of 850-1200 ℃, strain rate of 0.001-1 s<sup>-1</sup>, and true strain of 0.9 was studied by using Gleeble-1500D thermal simulation testing machine.The physically based flow stress model...
