Effect of Microstructure and Texture on Anisotropy and Mechanical Properties of SAE 970X Steel Under Hot Rolling

This paper presents the effect of microstructure and crystallographic texture by developed in hot rolling and different post-treatments on anisotropic and mechanical properties of SAE 970X steel. The experimental results showed that the hot-rolled sample followed by quenching and consequent tempering at 700 A degrees C led to a significant improvement in anisotropic and mechanical properties. This happened due to the reduction in the number of grains oriented with {001} planes parallel to normal direction. Also, the formation of new strain-free and recrystallized grains associated with {111}//ND and {110}//ND directions improved the mechanical properties. These grains corresponded to the close-packed planes in BCC structure as well.
