摘要

Intensive studies show that the best glass-forming ability (GFA) is presented as the Fermi surface made contact with pseudo-Brillouin boundaries. Via surveying the GFA of electronic simple Ca-Mg-Cu metallic glass system, we find that the best GFA is presented as the free electrons per atom (e/a) equals to 1.75, which is closed to the value of 1.8 proposed for the ideal amorphous state. The pseudo-gap or minimum in the density of states at the Fermi surface proposed by nearly free electron theory has not been observed in the Ca-Mg-Cu system. Our results indicate that the free electron concentration is an important but not the sole factor for influences in the glass formation.
