Rotary Piercing Experiment and Heat Treatment of β Titanium Alloy

Abstract:

A rotary piercing technique is one of the effective methods to fabricate seamless tube of less-deformable alloy. The research on the technique using the rotary piercing method to produce Ti26 high-strength titanium tube was performed. The distribution of strain and parameters during rotary piercing was analyzed. Microstructure, properties and fracture surface of the tube were studied after annealing treatment in argon, induction and vacuum. The results show that the high-quality tube of β titanium alloy can be obtained by the rotary piercing technique, and the induction annealing technique is an efficient heat treatment for the tube.
