In the present work, the effect of alloying elements on the phase transformation which are formed by cooling effect in CuAl, CuAlMn, and CuAlMnZn (wt%) alloys are investigated using scanning electron microscopy (SEM) and vibrating sample magnetometer (VSM) characterization techniques. From SEM observations, the martensite formation with different morphologies is observed in these alloys. But the results of the scanning electron microscope investigations presented in this work have not formed the precipitates in the CuAl alloy with Mn or Zn additions. We found that magnetic saturation and coercivity values decreased with the addition of Mn and Zn elements to the CuAl alloy. The findings confirmed the variation in magnetic properties, which occurred in the result of adding different alloying elements.
