Title:

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

Document Type and Number:

WIPO Patent Application WO/2013/058504

Kind Code:

A3

Abstract:

The present invention relates to a non-heat treated magnesium alloy sheet which can substantially reduce casting defects such as center segregation and inverse segregation and has excellent formability when compared with a conventional commercial magnesium alloy sheet by controlling an alloy composition. The magnesium alloy sheet according to the invention comprises 1-3 wt% of Al, 0.5-3 wt% of Sn and the remaining amount of magnesium, and the difference of the mean value of Vickers hardness (Hv) caused by center segregation and inverse segregation is 10Hv or less.
