成功地用真空扩散焊法获得了Ｔｉ６Ａ１４Ｖ／Ａｌ２Ｏ３的连接界面。分析了不同温度下的界面结构、界面反应情况，同时用压痕法初步偿派了界面残余应力分析。结果表明，在８００℃时扩散焊界面上没有显著的化学反应，随着温度的提高，界面上Ｔｉ６Ａ１４Ｖ和Ａｌ２Ｏ３反应生成ＴＩＡｌ、Ｔｉ２Ａｌ、Ｔｉ３Ａｌ与Ｔｉ组成的脆性混合过渡层。该过渡层，并通过氧的固溶使基体金属脆化；压痕裂纹扩展方式可以在一定程度上反映残余应力的局部分布特征。
Successfully using vacuum diffusion welding Ti6A14V / Al2O3 connection interface. The interfacial structure and interfacial reaction under different temperatures were analyzed. At the same time, the indentation method was used to analyze the residual stress of the interface. The results show that there is no significant chemical reaction at 800 ℃ diffusion interface. With the increase of temperature, Ti6A14V and Al2O3 react with each other to form a brittle transition layer consisting of TIA1, Ti2Al, Ti3Al and Ti. The transition layer, and through the solid solution of oxygen to the matrix metal embrittlement; indentation crack propagation mode to some extent, reflect the local distribution of residual stress characteristics.
