Effects of Deformation Rate on Microstructure and Tensile Properties of Cold Rolled Ti-3Al-2.5V Alloy Tube
Effects of deformation rate on microstructure and tensile properties of cold-rolled Ti-3Al-2. 5V alloy tube were studied. The microstructure was observed by optical microscope and tensile properties were evaluated with a tensile tester. The results show that the microstructure of cold-rolling Ti-3Al-2.5V alloy tube was bacillarstructure and the crystal preferred orientation became more and more significant with increasing the cold rolling deformation rate. The tensile strength increased a small amount but the strain remarkably decreased with the cold rolling deformation rate increasing from 30％ to 70％. Based on the calculated and experimental result,the range of the recrystallization temperature is determined. Our results are important to develop the high performance Ti-3Al-2. 5V alloy tubes and stabilize the production process
