通过875°C的热速处理技术，获得了Al-13 wt.%在不添加任何变质元素的情况下对硅合金进行了变质处理。Al-13 wt.%的熔体的结构用高温X射线衍射仪研究了在625°C ~ 1250°C温度范围内加热的Si合金的热变形。温度升高到775 ℃，合金的原子密度和配位数缓慢增加。这些参数在775°C至875°C的温度范围内发生突然变化。讨论了改性后的固态结构与熔体结构的关系。
By thermal-rate treatment technology at 875°C, the structure of an Al–13 wt.% Si alloy is modified without any addition of modifying elements. The structures of the melt of the Al-13 wt.% Si alloy heated in the temperature range from 625°C to 1250°C, were investigated using a high temperature X-ray diffractometer. Increasing the temperature up to 775°C, the atomic density and the coordination number of the alloy increase slowly. A sudden change in those parameters occurs in the temperature range from 775°C to 875°C. The relationship between the modified solid structure and the melt structure is discussed.
