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.
