英文摘要	The non-dendrite or spherical grains microstructure of AZ91D magnesium was obtained using the isothermal treatment technique and the thixo-casting process were studied under semi-solid state. The specimens with good properties were obtained and analyzed. The effects of injection speed and additional pressure on tensile strength, elongation rate and microstructure of specimens were investigated. The results show that the mechanical properties of alloy can be improved with the increase of injection speed and additional pressure. While the additional pressure is 35 MPa and the injection speed is 4.5 m/s, the tensile strength and elongation rate can reach 237.5 MPa and 4.8%, respectively. Through the microstructure analysis, the semi-solid thixo-casting most obviously refines the crystal grain. The solid phase particles in the semi-solid ingot may be broken into pieces again and the liquid phase may be sprayed and solidified during filling process due to most high shearing strength.
