In this study, a theoretical model is developed to characterize the quantitative effect of temperature on the hardness of pure FCC and HCP metals. The model is verified by comparison with the available experimental results of Cu, Al, Zn, Mg, Be, Zr, Ni, Ir, Rh, and Ti at different temperatures. Compared with the widely quoted Westbrook model and Ito–Shishokin model which need piecewise fitting to describe experimental values, the present model merely needs two hardness values at different temperatures to predict the experimental results, reducing reliance on conducting lots of experiments. This work provides a convenient method to predict temperature-dependent hardness of pure metals, and it is worth noting that it can be applied to a wide temperature range from absolute zero to melting point.

纯 FCC 和 HCP 金属的温度相关硬度建模

在这项研究中，开发了一个理论模型来表征温度对纯 FCC 和 HCP 金属硬度的定量影响。该模型通过与Cu、Al、Zn、Mg、Be、Zr、Ni、Ir、Rh和Ti在不同温度下的可用实验结果进行比较来验证。与广泛引用的 Westbrook 模型和 Ito-Shishokin 模型需要分段拟合来描述实验值相比，本模型只需要两个不同温度下的硬度值来预测实验结果，减少了对进行大量实验的依赖。这项工作提供了一种方便的方法来预测纯金属的温度相关硬度，值得注意的是它可以应用于从绝对零点到熔点的宽温度范围。
