Abstract

Abstract

In this study, biaxial tensile tests were conducted on the commercial pure titanium plates using cruciform specimens. The impact of biaxial tensile stress state on the mechanical properties was explored through Digital Image Correlation (DIC) to capture the strain response. The effect of biaxial tensile stress states on the mechanical properties of specimens was discussed. Compared to uniaxial mechanical properties, the biaxial loading material strength demonstrated a significant improvement. When the loading rates of X-axis and Y-axis are equal, the yield strength and tensile strength of the material reach the maximum. Electron Back Scatter Diffraction (EBSD) was further employed to analyze the influence of the biaxial load ratio on twinning behavior. Under uniaxial tension along the rolling direction (RD) or transverse direction (TD), the volume fraction of twins was found to be small, while there were more twins under biaxial loading and a maximum volume fraction of twins under equal load. Notably, when the load in the transverse direction exceeded that in the rolling direction, the volume fraction of tension twins surpassed that of compression twins.
