Abstract

In the present work, austenitic stainless steel has been forged to a strain level of ~0.4 at constant temperatures ranging from 900–1200°C with strain rates of 10 and 100 s–1. The resultant microstructure was analyzed using the electron back-scattering diffraction technique. For both the strain rates, deformation at 900°C produces deformed microstructure with serrated grain boundaries, especially for 10 s–1. The increase in forging temperature develops microstructure consisting of strain-free grains with a high fraction of special boundaries. The potentiodynamic polarization test of the deformed samples suggests a rather scattered corrosion rate with respect to strain rate and temperature. An attempt has been made to relate corrosion rate to the developed microstructure in terms of kernel average misorientation (KAM), boundary length and crystallographic texture.
