Effect of Age Hardening on the Mechanical Properties, Microhardness, and Corrosion Resistance of Zn-Cu-Al Shape Memory Alloy

Nowadays, shape memory alloys (SMA) are widely employed in various engineering applications, particularly in the fields of vibration control, electrical sensors, robotics, and aircraft. The primary issue stems from their mechanical properties' weakness. Thus, the goal of this research is to improve the mechanical qualities by using age hardening. Cu-Zn-Al shape memory alloy was created in this paper. Specimens of the Cu-Zn-Al shape memory alloywere subjected to general microstructure, microhardness, and corrosion tests throughout the as-cast and after-age hardening processes.It was discovered that there was a noticeable improvement in microhardness, which rose by 25.17% following age hardening and 19.8% following corrosion.
