摘要

Hot isothermal plane strain compression (PSC) tests were carried out on a 12Cr-10Ni martensitic precipitation-hardenable (PH) stainless steel, in the temperature range of 750-1050 A degrees C, to study microstructural evolution during large strain deformation. The nature of stress-strain curves varies with Zener-Holloman parameter (Z) with specimens deformed at high Z showing steady-state behavior and those deformed at lower Z showing flow softening. Prior austenite grain size (PAGS), d, exhibited a strong correlation to Z showing a bilinear behavior represented as: d = (1803.9)Z (-0.094) for high Z deformation and d = (1456.2)Z (-0.058) for low Z deformation. Based on the above study, it is recommended to thermomechanically process 12Cr-10Ni steel at Z aeyen 10(22) for obtaining products with good strength-toughness balance.
