Abstract

ABSTRACT: In the present study, to achieve grain refinement and enhance the mechanical properties of Al-2Mg alloy, ultrasonic treatment (UT) has been applied to the melt. The effects of this treatment on the microstructure, porosity alleviation, and mechanical properties of Al-2Mg have been thoroughly investigated. A microstructure study of the Al-2Mg UT alloy has revealed a noteworthy enhancement in grain refinement, resulting in a 3-to-4-fold reduction in grain size as compared to a non-UT Al-2Mg alloy. After UT, the yield tensile strength, the ultimate tensile strength, and the microhardness of Al-2Mg alloy are increased by 21%, 34%, and 36% respectively, with a large improvement of 143% in the ductility.
