to investigate the hot deformation behavior of 17-7 ph stainless steel, hot compression tests were carried out at the temperatures of 950, 1050 and 1150 oc and strain rates of 0.001 s-1 to 0.1 s-1. accordingly, the hot working behavior was studied by the analyses of flow stress curves, work hardening rate versus stress curves, exponent- type constitutive equations and deformed microstructures. ...

the 17-4ph alloy is a martensitic stainless steel with 3–5 wt% cu, strengthened by the precipitation hardening. due to excellent mechanical properties, corrosion resistance and ease of heat treatment, this alloy has unique applications in nuclear power plants and marine constructions. in this paper, the influence of ageing heat treatment, solution annealing followed by ageing at 480, 550 and 62...
