Abstract: In response to the problems of coarse microstructures in conventional die-casting products, a novel semi-solid die-casting process was employed to conduct die-casting experiments on AM60B alloy. The microstructure and mechanical properties of both semi-solid die-casting and conventional die-casting products were tested and analyzed. The results show that for the semi-solid die-cast products, the Vickers hardness increases from 58.87 HV of conventional die-casting to 62.94 HV,with an increase of approximately 6.9%. The tensile strength rises from 159.42 MPa to 196.87 MPa, and the elongation increases from 4.03% to 6.59%. The fracture type is ductile fracture with a large number of dimples. Semi-solid die casting can increase the content of the Mg₁₇ Al₁₂ strengthening phase in the product from 0.114% to 0.674%, and the distribution is more uniform. The average grain size of semi-solid die cast products reduces from 19.7 μm of conventional die casting to 12.9 μm.
