摘要

采用惯性摩擦焊连接 Ti

AlNb 合金，分析了焊态和热处理后焊接接头的组织变化，研究了不同热处理制度对 Ti

AlNb 合金惯性摩擦焊接头显微组织的影响。结果表明：利用惯性摩擦焊技术可获得无缺陷、焊缝状态良好的 Ti–22Al–25Nb 合金焊接接头；温度和热处理时间共同决定了焊合区 O 相的数量和尺寸的变化，但是相比时间的变化，热处理温度的变化对 O 相的影响更为明显；当热处理温度处于 780~850℃时，焊合区 O 相的长大幅度较小，长大后的尺寸仍然远小于母材的 O 相尺寸；热力影响区 O 相呈现与焊合区相同的演变规律；随着温度升高，热处理时间增长，热影响区 O 相发生粗化现象，α

相未发生变化。

Abstract

AlNb alloy was welded by inertia friction welding. The microstructure changes of welded joints under welded condition and after different heat treatments were analyzed. The influence of different heat treatments on the microstructure of inertia friction welded joints of Ti–22Al–25Nb alloy was studied. The results show that the Ti–22Al– 25Nb alloy welded joint without defect and with weld in good condition can be obtained by inertial friction welding. The change of the number and size of O phase in the welding zone is determined by the temperature and duration of heat treatment. However

compared with the change of duration

the change of temperature during heat treatment has a more remarkable influence on O phase. After heat treatment at temperature between 780℃ and 850℃

the growth range of O phase in the welding zone is small

and the size after growth is still far smaller than that of the base material. The evo

lution of O phase in thermo-mechanically affected zone is the same as that in welding zone. With the increasing of heating temperature and prolonging of heating time

O phase in HAZ coarsens

while α

phase is of no change.
