摘要 利用单辊甩带技术制备快速凝固Mg-6Zn-1Y-1Ce薄带,并利用透射电子显微镜和能谱仪分析薄带组织。结果表明:薄带近辊面区域晶粒内部和晶界处分布着高密度颗粒,颗粒密度在中间区域和自由面区域有所降低;快速凝固合金主要由过饱和的--Mg固溶体、T相和W相组成,同时还存在少量的二十面体准晶相颗粒和Mg4Zn7相颗粒;其中T相为体心正交晶体结构,是由于体心正方结构的Mg12Ce相中部分Mg原子被Zn原子代替而形成的。 Rapidly solidified（RS） Mg-6Zn-1Y-1Ce ribbons were prepared by single roller melt-spinning technique.Transmission electron microscopy and energy dispersive X-ray spectroscopy were employed to characterize the microstructure of RS ribbons.The results show that there is high density of particles distributed within grains and at grain boundaries in the region near wheel side.The particle density is decreased in the middle region and free surface region.The alloy is predominantly composed of supersaturated--Mg solid solution,T phase and W phase;meanwhile,a few icosahedral quasicrystalline and Mg4Zn7 particles are also observed.The T phase is confirmed having a body-centered orthorhombic structure that is transformed from the body-centered tetragonal structure Mg12Ce phase due to the partial substitution of Mg atoms by Zn.
