摘要：
Stress-induced martensite transformation in Ti-Ni shape-memory alloys is a well-known phenomenon. In this work, acoustic emission (AE) data acquisition was conducted simultaneously with mechanical testing (loading-unloading) at room temperature. In addition to the mechanical properties of the Ti-Ni shape-memory alloy, the AE parameters of the specimen tensile process were analyzed. The results showed that AE parameters such as count, amplitude, and energy can indicate the damage process.
