通过845℃过热处理，在不添加任何变质元素的情况下，对Al-7Si-0.55 Mg合金的组织进行了变质处理。用差热分析方法研究了Al-7Si-0.55 Mg熔体在500~1000℃温度范围内的热行为。在809~845℃的温度范围内，熔体内发生放热反应，并讨论了熔体结构与微观结构的关系。
By superheat treatment at 845 °C, the microstructure of Al–7Si–0.55Mg alloy is modified without any addition of modification elements. The thermal behaviors of Al–7Si–0.55Mg melt heated in the temperature range from 500 °C to 1000 °C were investigated using DTA. An exothermic reaction in the melt was detected in the temperature range from 809 °C to 845 °C. The relationship between the microstructure and the melt structure is discussed.
