Temperature dependence of thermal conductivity of Al-Si-1%Fe alloys under heating up to 150 °C

Abstract

We have studied the temperature dependence of the thermal conductivity of a series of experimentally obtained aluminum-silicon alloys with different silicon addition and additional iron content of 1 % by weight. The article shows how the change in the silicon content affects the thermal properties of the experimentally obtained alloys at room temperature. Also, the article describes the character of the change in thermal conductivity when the samples are heated up to 150 °C. Based on the obtained data, we con clude that the alloy containing 4 % silicon by weight is the most prospective for usage as a material for solving heat transfer problems.
