Abstract (en)

[origin: EP2319949A1] The present invention has as its object to provide an Mg-based alloy cold worked member which can remarkably lower the load weight required for cold plastic working and enables practical usage of the same. The present invention is an Mg-based alloy cold worked member obtained by cold working an Mg-based alloy to form it into a predetermined shape, characterized by having a microstructure which includes crystal grains divided and made finer by cold working.
