Abstract
Ultrasonic effects on the microstructure evolution and the mechanical properties of AZ80 alloy were investigated. The results indicate that in the case of the ultrasonic melt treatment, the primary α-Mg phases is transformed from coarse dendrites to nearly fine equiaxed grains, and the β-Mg17Al12 phase at α-Mg boundaries is refined and becomes discontinuous. Besides, the tensile properties of AZ80 alloy are apparently improved after ultrasonic melt treatment, in which 0.2% tensile yield strength, ultimate tensile strength and elongation are improved from 87 MPa, 118 MPa and 2.1% to 107 MPa, 170 MPa and 5.4%, respectively.
