Ce元素的加入使得Al84Mg10Ce6熔体产生了结构突变

增强了铝基合金非晶形成能力

850℃熔体通过熔甩工艺制得非晶态薄带。

Abstract

The relationship between the viscosity of Al84Mg10Ce6 alloy melt and temperature was analyzed by viscosity measurements

X-ray diffraction and DSC analysis. Through observing the glass forming ability of the alloy ribbon

the relationship between different over-heating temperature and its glass forming ability of alloy melt was described. The results show that the element Ce addition results in the abnormal change of Al84Mg10Ce6 alloy melt structure

enhancing the glass forming ability of Al-based alloy. GFA of Al-Mg series alloys exhibits the relation with melt temperature

where amorphous Al ribbon can be prepared by melt-spinning technology at 850 ℃.
