摘要:

分析了Zr-Al-Co合金系中玻璃转变温度(Tg)、晶化温度(Tx)和约化玻璃转变温度(Tg/Tm)与电子浓度值(e/a)、原子尺寸判据(λn)、混合焓(△Hchem)和混合熵(△S)的关系.结果表明:可以用多元回归的方法研究Tg、Tx和Tg/Tm与e/a、λn、△Hchem和△S的关系,回归结果都是显著的;通过F-检验,剔除e/a和λn,仅用△Hchem和△S足以解释响应变量Tg、Tx和Tg/Tm,简化模型的方法是可行的;只用△S或△Hchem解释响应变量Tg、Tx和Tg/Tm是不可靠的,在某些文章中只用△H来判断非晶形成能力的方法是不可靠的.

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.
