| 摘 要： | 通过两种工艺锻制了Ф350mm的大规格TC17钛合金棒材，比较了经两种工艺锻制的棒材的显微组织、力学性能及探伤杂波水平。研究结果表明，在单相区采用镦拔变形使变形量大于60％，并在两相区进行拔长，使变形苗大于65％，再经840℃×2h／AC＋800℃×4h／WC＋630℃×8h／AC热处理，可得到各项力学性能均符合GJB2218A-2008标准要求且探伤杂波水平可达（b3．2mm-9～-12dB的＋350mmTC17钛合金棒材。

| Abstract: | Forging th350 mm TC17 titanium alloy bars through two schemes, then compared the microstructures, mechanical properties and flaw detection levels of the bars. The results show that, deformed more than 60% using upsetting and stretching forging process in single-phase region and then deformed more than 65% using stretching forging process in dual-phase region, continued with the heat treatment of 840 ℃ ×2h/AC ＋ 800 ℃ ×4 h/WC ＋630 ℃ × 8 h/AC, the mechanical properties of bars could meet the GJB 2218A--2008 standard and the flaw detection level was Ф3.2 mm -9 - - 12 dB. |
