ABSTRACT:
A method for the production of a superplastic Mg-based composite material comprises preparing a composite material consisting of ceramic particles formed of at least one compound selected from among TiC, AlN, Si.sub.3 N.sub.4, and TiB.sub.2 and a matrix formed of a magnesium alloy, dispersing the ceramic particles in the matrix, hot extruding the composite material, and then hot rolling the resultant extrudate; and a superplastic Mg-based composite material produced by the method.
