摘要:

为探究Er、Si对铝基储热合金导热系数和相变储热值的影响，制备了Si的质量分数分别为12%、14%、16%，上述Si含量条件下，Er的质量分数分别为0.2%、0.4%、0.6%、0.8%的合金。根据实验测得的比热容、热扩散系数和密度，通过计算得到合金的导热系数，同时测量了合金的相变潜热，运用理论模型对合金的相变潜热进行计算，通过方差分析Er和Si含量对合金相变潜热的影响。分析结果表明，Er可以有效改善Al-Si合金中的初生Si形态，细化组织；Si含量为16%时，加入0.2%、0.6% Er的合金相变潜热分别为414.8和406.5 J/g。理论模型计算表明，考虑组元固-液相之间的比热容差对熵的贡献时，得到的合金相变潜热较未考虑的计算结果误差更小；对Al-12Si-xEr、Al-16Si-xEr相变潜热理论计算模型进行了修正，修正模型计算得到的合金相变潜热值和实测潜热值更为吻合。方差分析显示，在显著性水平p=0.05的条件下，Si含量对材料相变潜热有显著影响。

Abstract：

In order to investigate the effect of Er and Si on the thermal conductivity and latent heat of phase transformation of Al-based heat storage alloy, the alloys with Si contents (mass fraction) of 12%, 14% and 16% were prepared. The Er contents of the alloys were 0.2%, 0.4%, 0.6% and 0.8%, respectively. According to the specific heat capacity, thermal diffusivity and density measured by experiments, the thermal conductivity of the alloy was calculated. In addition, the latent heat of phase transformation of alloy was measured and calculated theoretically by using empirical formula. The influence of Er and Si contents on the latent heat of transformation was analyzed by variance. The results show that Er can effectively improve the morphology of primary Si and refine the microstructure in Al-Si alloy. When the content of Si is 16%, the latent heat of the alloy is 414.8 and 406.5 J/g respectively when adding 0.2% and 0.6% Er. When the contribution of the specific heat capacity difference between solid and liquid phases to entropy is considered, the calculated latent heat of phase transformation of the alloy is smaller than that not considered. The theoretical calculation models of the latent heat values of Al-12Si-xEr and Al-16Si-xEr are modified, and the latent heat values calculated by the modified model are more consistent with the measured values.The analysis of variance showed that under the condition of significant level p=0.05, the content of Si has a significant effect on the latent heat of phase transformation of the material.

Key words： Er Si aluminum-based heat storage alloy thermal conductivity latent heat of phase transformation
