摘要
The effect of 2% Fe addition on the microstructure and mechanical properties of Ti-25V-15Cr-2Al-0.2C alloy(mass fraction) was studied. It is found that the addition of 2% Fe seems to have no obvious effect on the microstructure of the alloy, but results in a significant change in mechanical properties. Compared with the alloy without Fe addition, the alloy with 2% Fe addition exhibits remarkable higher tensile strength and creep resistance, whereas the ductility is relatively lower at room temperature. The significant changes in mechanical properties can be rationalized by the decrease of stacking fault energy caused by the addition of 2% Fe.
