Abstract

An experimental study of the heat transfer coefficients of Mg–Ca eutectic alloys with a calcium content of 10.5 and 73.0 at % is carried out. These alloys are considered as promising biodegradable and ultralight construction materials. In the course of the study, new reliable experimental data on thermal conductivity (\(\lambda\)) and thermal diffusivity (\(a\)) are obtained in the temperature range 300–\(571\ldots 695\) K of the solid state. The estimated errors of the obtained data are 3.0–3.4% and 2.0–2.4% for \(\lambda\) and \(a\), respectively. Reference tables and recommended temperature dependences of the studied properties are developed, which can be used for various scientific and practical applications.

固态 Mg-Ca 共晶合金的导热率和热扩散率

摘要

对钙含量为 10.5 和 73.0 at% 的 Mg-Ca 共晶合金的传热系数进行了实验研究。这些合金被认为是有前途的可生物降解和超轻建筑材料。在研究过程中，在 300– \(571\ldots 695\)  K 的温度范围内获得了新的可靠的导热系数 ( \(\lambda\) ) 和热扩散系数 ( \(a\) ) 实验数据。固态。对于\(\lambda\) 和 \(a\) ，所获得数据的估计误差分别为 3.0–3.4% 和 2.0–2.4%  。开发了所研究特性的参考表和推荐的温度依赖性，可用于各种科学和实际应用。
