摘要：

The Mg-Mg2Si composite processed from rapidly solidified ribbons exhibited high strength of about 500 MPa at room temperature and superplastic behavior at high strain rates of 10-1 ~ 1 s-1 at 773 K. The high strain rate superplasticity is attributed to the very small grain size of about 1 μm. © 1995.
