摘　　要：The objective of this study is to determine the isothermal section at 400℃ of the Mgsingle bondCesingle bondSr system.In this study,the constitution of the Cesingle bondSr system and the Mgsingle bondCesingle bondSr system have been investigated over the entire composition range using X-ray diffraction(XRD),field emission scanning electron microscope(SEM)and energy dispersive spectroscopy(EDS).No any new binary compound has been found in the Cesingle bondSr system and no ternary compound has been found in the Mgsingle bondCesingle bondSr system also.Nine three-phase regions have been experimentally observed.Six binary phases Mg_(2)Sr,Mg_(23)Sr_(6),Mg_(38)Sr_(9),Mg_(17)Sr_(2),Mg_(12)Ce,Mg_(41)Ce_(5) are detected dissolving about 3-7 at.%the third element.This study first detected the experimental data of the Cesingle bondSr binary system and determined the isothermal section at 400℃ of the Mgsingle bondCesingle bondSr ternary system.
