摘要

提出了一个模型，可以计算玻璃显微硬度在从软化温度到绝对零度的整个温度范围内的温度依赖关系。计算采用玻璃化焓的温度依赖性及其在玻璃化转变温度下的显微硬度值。以玻璃态硒为例对该模型进行了验证。为此，测量了硒的显微硬度对软化温度的温度依赖性，软化温度达到100 K，比其德拜温度低50 K。因此，建立了玻璃的强度和热力学性质之间的关系。

Relationship of Temperature Dependences of Microhardness and Enthalpy of Glass on the Example of Selenium

A model is proposed that makes it possible to calculate the temperature dependence of the microhardness of glass over the entire temperature range from the softening temperature to absolute zero. The calculation uses the temperature dependence of the glass enthalpy and the value of its microhardness at the glass transition temperature. The proposed model is tested on the example of glassy selenium. For this, the temperature dependence of the microhardness of selenium on the softening temperature up to 100 K, which is 50 K below its Debye temperature, is measured. Thus, a relationship is established between the strength and thermodynamic properties of glass.
