Abstract This work mainly studies the anisotropy of microstructure and tensile behavior of 500 MPa grade high strength low alloy steel (HSLA steel) for automotive structural components. Microstructure, texture, tensile properties, and fracture behavior of CR500LA alloy specimens with rolling directions of 0°, 45°, and 90° were studied by means of scanning electron microscopy (SEM), tensile testing machines, and other equipment. The anisotropy of CR500LA alloy was predicted using the Hill48-σ, Hill48-r, and Yld2000-2d yield criteria. The results indicate that the alloy is mainly composed of ferrite and pearlite. The main types of textures are {111}〈110, {111}〈112〉, {001}〈110〉, and {112}〈110〉, with the α fiber texture {112}〈110〉 being the predominant. As the angle with the rolling direction increases, the tensile strength first decreases and then increases, while the plasticity and r-value first increase and then decrease. The anisotropy of alloys is mainly caused by differences in texture types and its proportions. Yld2000-2d yield model provides more accurate predictions for the anisotropy of CR500LA alloy. Tensile fracture is a typical ductile fracture composed of a large number of dimples.

Key words： high strength low alloy steel CR500LA microstructure tensile behaviour anisotropy
