Gr12 titanium alloy seamless tube
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 can form a cathode overvoltage lower than pure titanium, which obviously improves industrial purity. Titanium's resistance to crevice corrosion and pitting corrosion is rich in raw material resources and low cost compared with titanium alloys of other components. It is widely used in the chemical industry and vacuum salt industry. In addition, TA10 titanium alloy also has the characteristics of stable structure, strong oxidation resistance, good weldability and high plasticity.
Preparation of titanium alloy seamless pipe by cross rolling
The processing technology of titanium and titanium alloy seamless tube blanks mainly includes extrusion method and cross-rolling perforation method. The preparation of TA10 titanium alloy industrial production tube blank is mainly extrusion, and there are few reports on the cross-rolling perforation. Compared with the extrusion production seamless pipe, the cross-rolling perforation method not only has a short process and high efficiency, but also improves the material utilization rate, reduces the cost, and conforms to the concept of energy conservation and environmental protection. The company adopts two-roll cross-rolling and perforating process to prepare TA10 titanium alloy seamless pipe, and explores the heat treatment process of seamless pipe to obtain the pipe with comprehensive mechanical properties.
