Thermal Stability and Liquid Corrosion of Eutectic Alloy Al-Mg-Zn as Latent Heat Storage Materials
摘 要
研究了潜热储蓄材料Al-34%Mg-6%Zn合金加入铍后,在不同熔化/凝固热循环次数下的热稳定性及对SS304L不锈钢和C20碳钢的腐蚀性.结果表明:在1 000次热循环后,合金熔化温度下降了3.06 ℃,熔化潜热减少1.95%,该合金作为潜热储能材料有着很好的热稳定性;对于长期的储能应用,SS304L钢(腐蚀率为0.10 mm/a)比C20钢(0.18 mm/a)更能耐该合金的腐蚀,可作为容器材料使用.

Abstract
The thermal stability of Al-34%Mg-6%Zn alloy with trace amount of beryllium as thermal energy storage materials under the conditions of a large number of melting / solidification thermal cycles and the corrosion of the alloy with respect to stainless steel (SS304L) and carbon steel (steel C20) during thermal cycle process were studied.The investigated alloy as latent heat storage materials had good thermal stability since the melting temperature and the latent heat of fusion were decreased by 3.06 ℃ and 1.95% for the alloy after 1 000 cycles,respectively.The results of corrosion test showed that SS304L (corrosion rate 0.10 mm/a) might be considered to be more suitable than C20 (corrosion rate 0.18 mm/a) in long-term thermal storage applications.
