Abstract

Elastic modulus anisotropy with respect to sheet rolling direction was calculated, using X-ray diffraction determined texture components and their known individual anisotropies, for a deep drawing grade steel in the cold rolled as received and three heat treated conditions. The calculated elastic modulus anisotropy was compared to mechanically measured modulus values, at 0, 45 and 90° to the rolling direction, and ultrasonic velocity anisotropy, measured using an electromagnetic acoustic transducer (EMAT) system. It was found that the EMAT velocity anisotropy matched the measured modulus variation with angle, with differences between the as rolled and heat treated conditions being observed. However the predicted modulus variation did not show much difference between the as rolled and heat treated conditions, despite different textures being measured, resulting in a slight discrepancy with the EMAT velocity and measured modulus values at 90° for one heat treatment condition.
