    摘要:

    利用兩輥斜軋穿孔機進行了Ti26高強鈦合金管坯的斜軋穿孔試驗，分析了穿孔過程中應(yīng)變的分布規(guī)律及工藝參數(shù)，并研究了氬氣保護、感應(yīng)退火、真空3種不同熱處理方式對管坯組織及性能的影響。結(jié)果表明：選擇合理的穿孔工藝參數(shù)，可以獲得優(yōu)質(zhì)的β鈦合金管坯，感應(yīng)退火處理是穿孔管坯一種有效的均勻化熱處理工藝。

    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.
