Abstract

This is an investigation on examination of deformation induced surface roughening behavior of two AISI 304 quality austenitic stainless steel sheets, having ASTM grain size numbers of 7 and 8. In as-received condition, surface roughness of the fine-grained steel was higher than that of the coarse-grained steel, where the roughness increased gradually during plastic deformation., The rate of roughening increased with increasing grain size. Coarse-grained steel exhibited rougher surface than fine-grained steel after longitudinal strain of 11%, during uniaxial tensile loading.
