| Abstract: | The(Mg2Ni+Mg3Sb2)/Mg composites with different Ni content were prepared by powder metallurgy method,and the prepared composites were deformed by hot pressing process.The effects of hot pressing on the microstructure and mechanical properties of(Mg2Ni+Mg3Sb2)/Mg composites were investigated.The results reveal that the hot press deformation can refine the matrix Mg particles,and improve the uniformity of Mg3Sb2 and Mg2Ni microstructure distribution as well as eliminating the defects such as voids and cracks in the composites and improving the density,so significantly increasing the mechanical properties of the composites. |
