Microstructure and Mechanical Properties of Ti-B20 Alloy after Solution and Aging Treatment

The microstructure and mechanical properties of new type Ti-B20 alloy after different heat treatment were studied. The results show that the yield ratio of Ti-B20 alloy after solution treatment is higher and the tensile plastic is better. The higher the solution temperature, the lower the strength of the alloy, the better the plastic. When the solution temperature exceeds the phase transformation point of the alloy, the reducing rate of area reaches 55% and it fits for the depth plastic processing. An excellent strength and ductility values of the alloy after solution aging treatment is that σb ≥1400 MPa, δ≥ 8%.
