- Abstract:
-
The relationships between glass transition temperature (Tg), crystallization temperature (Tx) and reduced glass transition temperature (Tg/Tm) and electron concentration value (e/a), atomic size criterion (λn), mixed enthalpy (△Hchem) and mixed entropy (△S) in Zr-Al-Co alloy series were analyzed. The results show that the relationships between Tg, Tx and Tg/Tm and e/a, λn, △Hchem and △S can be studied by multiple regression, and the regression results are significant. Through the F-test, e/a and λn are eliminated, and only △Hchem and △S are sufficient to explain the response variables Tg, Tx and Tg/Tm, and the method of simplifying the model is feasible. It is unreliable to use △S or △Hchem to explain the response variables Tg, Tx and Tg/Tm, and in some articles it is unreliable to use only △H to determine the amorphous formation ability.
