Mg BASE ALLOY

Abstract

An Mg base alloy of this invention is characterized in that Ag is contained in an amount of not more than 1.98 at % as an additive material other than Zn. There is provided an Mg base alloy having not only a practically sufficient strength but good ductility at room temperature to an extent that it has hitherto been unable to be desired and having small anisotropy in strength characteristics.

1 . An Mg base alloy containing Mg as a main material and Zn as an additive material. which is characterized in that Ag is contained in an amount of not more than 1.98 at % as an additive material other than Zn. 
   
   
       2 . The Mg base alloy according to  claim 1 , which is characterized in that Ca is further contained in an amount of not more than 0.61 at % as an additive material other than Zn and Ag. 
   
   
       3 . The Mg base alloy according to  claim 2 , which is characterized in that Zr is further contained in an amount of not more than 0.17 at % as an additive material other than Zn, Ag and Ca. 
   
   
       4 . The Mg base alloy according to any one of  claims 1  to  3 , which is characterized in that a grain size thereof is from 0.1 μm to 25 μm.
