摘要：

TA15钛合金板材是航空航天领域的常用材料。为了在降低生产成本的基础上，制备出综合性能优异的TA15钛合金板材，通过多火次换向镦拔加一火次大变形换向轧制制备了TA15钛合金厚板，并在不同温度下进行退火，分析其微观组织与力学性能，并建立了TA15钛合金厚板退火温度与性能之间的关系，确定出最佳的退火制度。研究结果表明，在830 ℃/1 h/AC制度下进行退火生产出的TA15钛合金板材表现出最佳的综合性能，最终在生产成本降低的同时，优化了板材的综合性能。

TA15 titanium alloy plate is very frequently used in the aerospace industry. Therefore, in order to prepare TA15 titanium alloy plate with excellent comprehensive performance on the basis of reducing production cost, the TA15 titanium alloy thick plate was prepared by multi-fire reversing upsetting-drawing and one-fire large deformation reversing rolling, and annealed at different temperatures, then the microstructure and mechanical properties were analyzed to establish the relationship between annealing temperature and performance of TA15 titanium alloy thick plate and determine the optimal annealing system. The research results show that the TA15 titanium alloy plate produced by annealing at 830 ℃/1 h/AC system show the best comprehensive performance, and finally the comprehensive performance of the plate is optimized while the production cost is reduced.
