摘要(Abstract)：

在钛基复合材料制备过程中，热等静压工艺使Ti65合金包套性能下降，导致钛基复合材料构件服役性能降低。为优化钛基复合材料性能及制备工艺，采用扫描电镜(SEM)、电子背散射衍射(EBSD)和电子万能试验机等分析了热处理工艺与热等静压对Ti65合金的显微组织及室温、高温拉伸性能的影响，分析了不同状态下Ti65合金的室温和高温拉伸断裂机制。结果表明：Ti65合金的锻态和热等静压态的组织相似，均为典型的双态组织，经过热处理后组织中出现了大量的β转变组织；热等静压处理导致Ti65合金的屈服强度下降，热处理会提升其抗拉强度；热等静压处理后Ti65合金的室温和高温拉伸断裂机制均为韧性断裂；在钛基复合材料热等静压成型前Ti65合金包套无需热处理，成型后适当的热处理可提升Ti65合金包套的性能。
