Abstract
The compositional dependence of glass formation and thermal and elastic properties was clarified for the ternary La-Al-Co bulk glass-forming system. The existing linear correlation between La concentration and characteristic temperatures, i.e., the glass transition temperature Tg and the onset temperature of crystallization Tx, as well as the elastic moduli in this system can give a useful guideline for the chemical design of desirable bulk metallic glasses (BMGs) with tunable physical properties in advance. The relationship between Tg and elastic constants for the La-Al-Co BMGs can be quantitatively described using a microscopic model proposed by T. Egami.
