Relationships between microstructure and mechanical properties of Ti–3Al–5Mo–5V alloy

Through a statistical, quantitative analysis on microstructures of Ti–3Al–5Mo–5V alloy, the relationships among microstructures, mechanical properties, and shear bands (formed after rapid compression) were investigated systematically. The results show that the wires properties are strongly determined by their microstructure characteristics, such as the aspect ratio and the size of α platelet. Correspondingly, similar tendencies of variation occur in the curves of microstructure, mechanical properties of the billets, and shear bands width measured after billets compression. New indexes of mechanical properties such as shear band width and the crack initiation energy are expected to use for evaluating the wires qualities efficiently.
