Abstract
The deformation mechanism at room temperature in water quenched (WQ) and furnace cooled (FC) mild steels was investigated in a plane tilted 45° from the tensile direction, using electron back scattered diffraction, XRD, and TEM. The occurrence of (211) twinning was confirmed by pole figures and the slip systems were analyzed by variation in full width half maximum during tensile deformation. In WQ steel the deformation occurred through both (211) twinning and (110) slip in the low strain region, and by (211) slip in the high strain region. However, in FC the deformation was produced by both (211) twinning and (211) slip in the low strain region and (211) twinning and (110) and (211) slip in the high strain region in FC. †(Received May 27, 2016; Accepted June 23, 2016)
