Abstract

This study aimed to achieve enhanced mechanical compatibility of Ti-13Nb-13Zr alloy by producing submicrocrystalline microstructure without imposing severe strains. In order to find the optimum processing conditions, a series of compression tests was performed for initial martensite microstructure in strain ranges up to 0.8 and 1.4, the strain rate range of 10^-3 to 1s^-1 and the temperature range of 500-700°C. Based on the microstructural analysis, the submicrocrystalline (∼0.4μm) alloy consisting of high-angle grain boundaries was produced via dynamic globularization at temperature of 600°C, equivalent strain rate of 10^-1s^-1 and strain of 1.4, which showed about 25% enhanced mechanical compatibility as compared to the conventionally produced ones. The formation of submicrocrystalline microstructure at relatively low strain was investigated by examining the microstructure before and after dynamic globularization.
