Fabrication of bulk metallic glasses at the region of multiple quasi-peritectic reactions

We report that Ca-Cu-Mg bulk metallic glasses (BMGs) can be fabricated at the region of multiple quasi-peritectic reactions by a conventional copper mold casting method, demonstrating that finding a deep eutectic composition is not the sole solution for the fabrication of BMGs. Unusual relationship between the glass transition temperature and the elastic constants of these BMGs were discussed in comparison with other BMGs. These results have implications for exploring new BMGs and understanding the glass formation mechanism.
