主　　题：Biodegradable Mg alloys Hot rolling 

摘      要：In this study,four different Mg-Zn-Ca-Mn alloys were produced using gravity die casting *** content was kept constant in all alloys,while Zn and Ca were added in two different *** heat treatment was applied to all cast alloys and a specimen from each homogenized alloy was hot ***,mechanical properties,and corrosion behavior of the homogenized and hot rolled alloys were investigated as *** results were obtained;grain size decreased significantly with increasing Zn content,Zn promoted Ca 2 Mg 6 Zn 3 phase formation,corrosion resistance increased with increasing Zn/Ca atomic ratio,hot rolling resulted in much higher tensile strength but much lower ductility and *** the homogenized and hot rolled alloys,ZXM300-h alloy(hot rolled ZXM300 alloy)with its 146±2.5 MPa yield strength,229±3.7 MPa tensile strength,%1.6±0.1 elongation and 0.029 mm/*** corrosion rate exhibited the best mechanical properties and corrosion resistance to be used as a biodegradable alloy such as fracture bone plate material.
