英文摘要: Abstract(#br)Effects of Sb modification on the eutectic microstructure and tensile properties of hypoeutectic Al–11Mg 2 Si alloy were systematically investigated in this work. Eutectic Mg 2 Si phase in hypoeutectic Al–11Mg 2 Si alloy was successfully refined from the long rod-like structure into fine spherical morphology when introducing 0.2 wt% Sb, whereas 1.0 wt% Sb reversely led to the formation of coarse eutectic Mg 2 Si phase. Specifically, the elongation to failure in the 0.2 wt% Sb modified alloy was significantly improved to 9.7% as compared to the unmodified counterpart (1.5%), and the ultimate tensile strength increased from 183 MPa to 208 MPa. This result can be attributed to the spheroidization of eutectic Mg 2 Si phase with Sb modification, which greatly relieved the stress...
