The Gr12 titanium alloy seamless tube is prepared by the cross-rolling perforation method, which has the advantages of no wrapping and lubrication, no pollution to the environment, low mold consumption, high metal utilization rate, short process and low energy consumption. Through (870 ° C, 40 min, WC) + (500 ° C, 40 min, AC) heat treatment to improve the mechanical properties of the pipe, to meet the requirements of the national standard, for the industrialized mass production of the alloy provides a reference. Titanium and titanium alloys have excellent properties such as low density, high specific strength, high temperature resistance, corrosion resistance, non-magnetic, biocompatibility, etc. The products have been widely used in aviation, aerospace, shipbuilding, weapons, petroleum, chemical, medical, etc. field. The nominal chemical composition of TA10 titanium alloy is Ti-0.3Mo-0.8Ni (wt%), which is a kind of near-α titanium alloy. Its trace elements molybdenum and nickel
