Mechanical properties and microstructure have been investigated on a 17 vol% SiC paniculate-reinforced ZK60 magnesium-based composite (ASTM designation: ZK60/SiC/17p). The composite exhibits a high specific strength as well as a maraging steel, and limited ductility < 1%. In order to enhance the ductility under dynamic loading, additional extrusion was performed to homogenize the morphology in distributed reinforcements. It has been revealed that a homogeneous distribution of reinforcements is effective to enhance the ductility under dynamic loading.
