Experimental investigation of the isothermal section at 400 °C of the MgCeSr ternary system

The objective of this study is to determine the isothermal section at 400 °C of the MgCeSr system. In this study, the constitution of the CeSr system and the MgCeSr 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 CeSr system and no ternary compound has been found in the MgCeSr system also. Nine three-phase regions have been experimentally observed. Six binary phases Mg2Sr, Mg23Sr6, Mg38Sr9, Mg17Sr2, Mg12Ce, Mg41Ce5 are detected dissolving about 3–7 at.% the third element. This study first detected the experimental data of the CeSr binary system and determined the isothermal section at 400 °C of the MgCeSr ternary system.
