X Ray Diffraction studies using synchrotron radiation of Mg-based bulk metallic glasses

Full text: Metallic glasses have attracted many scientist and regained high interest because of recent production that reach to the dimension of 1 cm or even more. They have remarkable properties compared with conventional metallic alloy. In this paper, Mg-based metallic glass delivers special interest because provides new light material for structural applications. Significant amount of researches have been conducted mostly in Mg-Cu-RE systems of alloys. The target is to optimize glass forming ability. Mg58Cu31Gd11 alloys are produced by melt spinning and copper mold casting. The produced alloys composition has shown a fully amorphous state with a clear crystallization temperature is also observed. In-situ experiment during heating was also performed in ID11 beamline ESRF Grenoble. To support the work, a combination of SEM-EDS, DSC and conventional XRD experiment was also done. It is observed the presence of ternary compound inside the Mg58Cu31Gd11 alloy. (author)
