Synthesis of new glassy Mg-Ca-Zn alloys with exceptionally low Young's Modulus: Exploring near eutectic compositions

Abstract We report two new magnesium-rich glassy Mg-Ca-Zn alloys of one eutectic (Mg72Ca12Zn16) and another near eutectic (Mg63Ca15Zn22) composition. The glass-forming ability of the alloys is slightly lower than that of the Mg60Ca5Zn35 alloy which has been well explored earlier. The Young's Modulus of the new glassy alloys is exceptionally low (~35 GPa) and much lower than that of the Mg60Ca5Zn35glassy alloy (~50 GPa) indicating possible potential biomedical applications.
