摘要: 

采用无坩埚感应熔炼超声气体雾化法制备了成分为Ti-22Al-24Nb-0.5Mo(原子分数, %)的预合金粉末, 通过包套热等静压工艺制备了粉末Ti2AlNb合金。研究结果显示热等静压温度显著影响粉末Ti2AlNb合金的冶金质量, 需严格控制。对制备的粉末合金进行了热处理, 分析了热处理制度对粉末Ti2AlNb合金相组成、显微组织、拉伸及高温持久寿命的影响, 优选了粉末Ti2AlNb合金的热处理工艺。粉末Ti2AlNb合金高温持久寿命受多方面因素协同影响; 时效温度较低时(800-850℃), 随着时效温度的升高, 次生O相板条宽度和长度增加、α2相体积分数减少, 协同作用的结果是持久寿命增加; 时效温度较高 (850-900℃) 时, 次生O相尺寸、α2相体积分数变化不显著, B2相体积分数增加及α2相尺寸的增大对持久寿命的提高起了关键作用。

Abstract：

Pre-alloyed powder of Ti-22Al-24Nb-0.5Mo (atomic fraction, %) was prepared by crucibleless induction melting and gas atomization process. Then with the pre-alloyed powder, a powder metallurgical (PM) Ti2AlNb alloy was fabricated by a hot isostatic pressing route. The results show that the hot isostatic pressing temperature affects the metallurgical quality of PM Ti2AlNb alloys; the post heat treatment affects obviously the microstructure and the performance of the PM alloy; a good combination of tensile strength, ductility and rupture lifetime could be obtained through an optimized heat treatment process. It follows that the rupture lifetime of PM Ti2AlNb alloys was controlled by the interaction of multiple factors such as the sizes and volume fractions of α2, O and B2 phases after various heat treatments. With the increase of aging temperature (800~850℃), the size of secondary O phase increased and α2 volume fraction decreased, thereby the rupture lifetime was increased. With the increase of aging temperature (850-900℃), the size of secondary O phase and α2 volume fraction remain nearly constant. It was the increase of B2 volume fraction and α2 size that improve the rupture lifetime of PM Ti2AlNb alloys.
Key words： metallic materials    powder metallurgy    Ti2AlNb    rupture lifetime    near net shape manufacture
