摘要

利用激光增材制造技术制备出Ti-22Al-25Nb 合金薄壁试样，分析了沉积态和热处理态试样的宏观形貌、相组成和显微组织，以及不同制度热处理态试样的组织和室温拉伸性能。结果表明，沉积态试样相组成沿沉积高度方向呈现由B2+O+α

→ B2+O → B2 的变化趋势；热处理态试样的微观组织和相组成均匀，由B2、O、α

3 相组成；经930℃保温2h 空冷的固溶处理和800℃保温24h 空冷的时效处理后，合金室温拉伸性能好，抗拉强度为1017MPa，断后伸长率为6.0%。

Abstract

Thin-wall samples of Ti-22Al-25Nb alloy are prepared through the laser additive manufacturing process. The macro morphology

phase composition and microstructure for as-deposited and heat-treated samples are investigated. In addition

the microstructure and room tensile properties of Ti-22Al-25Nb alloy are analyzed after a series of heat treatments. The results indicate that for the as-deposited sample

the phase transforms as B2+O+α2→B2+O→B2 along the build-up direction

while the phase composition and microstructure of heat-treated sample become homogeneous

which is composed of B2

O and α2 phases. After solution treatment of 930℃ ×2h/air cooling followed by aging treatment of 800℃ × 24h/air cooling

the laser additive manufactured Ti2AlNb alloy shows better tensile properties with ultimate tensile strength of 1017 MPa and elongation of 6.0%.
