BTi-62421S高溫鈦合金的熱成形及超塑成形性能Hot forming and superplastic forming performance of?high-temperature BTi-62421S titanium alloy對新型高溫鈦合金B(yǎng)Ti-62421S進行卷圓、冷/熱沖壓成形、熱漲性、熱成形等實驗研究，獲得了該合金的熱成形性能；通過高溫超塑性拉伸試驗，獲得了該合金超塑性成形的最佳工藝參數(shù)，并進行該合金框架、舵面零件的超塑性成形試驗。結(jié)果表明：BTi-62421S鈦合金在(620±10)℃下保溫20~25 min可實現(xiàn)筒形件的熱漲形，在750 ℃左右可實現(xiàn)口框類零件的熱成形，但熱成形性能存在各向異性；該合金在溫度為920 ℃，應變速率為1.0×10?3?s?1時具有最佳超塑性能，伸長率達到448.5%，在此條件下可成形出滿足設計要求的舵面及框架樣件。
Experiments including crimping, cold pressing, hot pressing, hot bulging, hot forming were carried out to achieve the hot deforming performance of BTi-62421S alloy. The tensile tests under superplastic temperature were also carried out to determine the optimum parameters of superplastic forming. Furthermore, a BTi-62421S alloy frame and a rudder were superplastic deformed. The results show BTi-62421S alloy tube can be hot-bulged at (620±10) ℃for 20?25 min, and a big cage part can be hot-formed at about 750 ℃ although the alloy is anisotropic. BTi-62421S alloy has the optimal superplastic performance with the elongation of 448.5% when being deformed at the temperature of 920℃ and the strain rate of 1.5×10?4?s?1. A BTi-62421S titanium alloy frame and a rudder satisfying with the design requirements can be formed successfully under this condition.
