Abstract

Magnesium matrix composites with different volume fractions of Mg

by in-situ method were prepared.The Gibbs free energy at different temperatures and adiabatic temperature of different Sb contents were calculated

and the composites were examined by X ray diffraction（XRD）and differential scanning calorimetry（DSC）.The results reveal that the magnesium matrix composites with different volume fractions of Mg

can be prepared by in-situ method.The 3Mg+2Sb=Mg

reaction can be carried out spontaneously.When the Sb content is 7.7%

15.4%and 23.1%

the synthesis reaction of Mg-Sb cann’t occur spontaneously.The synthesis temperature of intermetallic compound Mg

is544.58℃

621.84℃and 666.14℃

respectively.
