NON-HEAT TREATED MAGNESIUM ALLOY SHEET WITH EXCELLENT FORMABILITY AT ROOM TEMPERATURE IN WHICH SEGREGATION IS MINIMIZED

摘要

Disclosed herein is a non-heat treatable magnesium alloy sheet, including: 1 ∼ 3 wt% of aluminum (Al); 0.5 ∼ 3 wt% of tin (Sn); and a balance of magnesium, wherein the maximum deviation of average Vickers hardness (Hv) thereof, caused by center segregation and inverse segregation, is 10 Hv or less.;The non-heat treatable magnesium alloy sheet can remarkably reduce a cast defect such as center segregation, inverse segregation or the like by alloy component control, and has excellent formability compared to that of a conventional commercially available magnesium alloy sheet.
