N2 - This paper reports investigation results of microstructure transformation and shape memory property in Cu-22Zn-7Al (wt%) shape memory alloy in the heat treatment process with the variable of various quench mediums. The alloy was made by the melting process of Cu ingot, yellow brass, and Al ingot. Molten metal was poured and solidified in a permanent mold. Then, solid Cu-22Zn-7Al alloy was heat treated by homogenizing and stress relief annealing. Martensite of the alloy was formed by heating Cu-22Zn-7Al in Beta phase temperature then continued by cooling in air, oil, water, and brine. Each cooling medium has a different effect on cooling rate. Chemical composition, microstructure, non-equilibrium transformation temperature, hardness, and shape memory properties were investigated in detail. The result shows that the martensite phase increases by enhancement of cooling rate. Alloy quenched by brine not only performs the best quality of martensite but also exhibits the highest shape memory recovery.
