摘要
采用铜辊旋淬法制备Mg65Cu25Y10金属玻璃条带,并在玻璃化温度附近对其进行时效处理。结果表明,对应不同的时效处理温度与时间,该合金条带具有不同的相组成。同时,时效处理对其室温塑性也有很大的影响,时效处理后条带的塑性变差。通过对时效处理前后条带的X射线衍射图谱和扫描电镜照片的分析,对Mg65Cu25Y10金属玻璃的晶化机理进行了初步探讨。
Mg65Cu25Y10 amorphous ribbons obtained by melt-spinning method were aged at temperatures nearby the glass transition one. Mg65Cu25Y10 alloy ribbons contain different phases after aging at different temperatures for different times. Meanwhile, the room temperature plasticity of the aged Mg65Cu25Y10 alloy ribbon degrades. According to the XRD and SEM images of different specimens, the crystallization mechanism of Mg65Cu25Y10 amorphous ribbon is briefly analyzed.
