This study aimed to reveal the interface behavior of iron-based shape memory alloy (Fe-SMA) strips bonded to metallic substrates in order to ensure the integrity of such joints. A series of single lap-shear tests was performed on Fe-SMA-to-steel adhesively bonded joints. The test results reveal that the bond strength can reach over 70% of the tensile strength of the Fe-SMA and the cohesive failure mode can be realized. It is identified that three energy dissipation mechanisms occurred during the debonding process, indicating that the experimentally obtained bond-slip relations represent more than the energy dissipation by the failure of the adhesive.

这项研究旨在揭示结合到金属基材上的铁基形状记忆合金（Fe-SMA）合金带的界面行为，以确保此类接头的完整性。在Fe-SMA与钢之间的粘结接头上进行了一系列的单搭接剪切试验。测试结果表明，结合强度可以达到Fe-SMA拉伸强度的70％以上，并且可以实现内聚破坏模式。可以确定的是，在脱粘过程中发生了三种能量耗散机制，这表明实验获得的粘结-滑动关系所代表的意义远大于粘合剂失效所造成的能量耗散。
