摘要

在Al-Si合金的基础上

优化设计并制备了3种不同成分的Al-Si-Cu-Mg铝基相变储热材料。采用X射线衍射（XRD）、扫描电镜（SEM）分析、差示扫描量热分析（DSC）等手段

对4种不同成分的铝基高温相变储热材料的微观组织、密度、相变温度、储热性能等进行了研究。结果表明

4种储热材料的相变温度都处于500～650℃之间

且相变潜热都在300J·g-1以上。Al-13Si合金储热材料具有较高的单位质量储热量;Al-Si-Cu-Mg合金储热材料具有较大的单位体积储热量。Mg能显著降低储热材料的相变温度

具有较好的扩大储热温度范围的作用。Cu能显著增大储热材料的密度

使其具有更好的单位体积储热性能。

Abstract

Three series of Al-Si-Cu-Mg phase-change thermal storage aluminum alloy materials with different components were prepared based on Al-Si alloy through optimizing design. With the help of X-ray diffraction （XRD）

scanning electron microscope （SEM） and differential scanning calorimetry （DSC）

the microstructure

density

phase change temperature and the thermal storage properties of these materials were investigated. The results indicate that the phase transformation temperature of the alloys prepared is in the range of 500 ℃

650 ℃ with the latent heat higher than 300 J·g-1. The Al-13Si alloy has the higher heat storage per unit mass

and the Al-Si-Cu-Mg alloys have the higher heat storage per unit volume. Mg element can be used to enlarge the thermal storage temperature range due to remarkably reducing the phase transition temperature. Cu element can increase the density of the thermal storage materials

which is responsible for better thermal storage properties per unit volume.
