Abstract:
The particles of Mg-Zn-Gd icosahedral quasi-crystal master alloy were added into the AZ31 alloy by the repeated plastic working (RPW) process in order to improve the mechanical properties of the AZ31 alloy at room temperature. The microstructure and tensile properties of composites were investigated by scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray diffraction (XRD), and tensile testing machine at room temperature. The results suggest that the RPW process can effectively refine the matrix and make the I-phase particles distribute uniformly. The ultimate tensile strength and the yield strength of the composites reach their maximum values of 362.3 and 330.5MPa, respectively, when the amount of I-phase particles added is 10%. Meanwhile, the elongation of the composites decreases sharply.
