Ce对高纯Mg-3Al合金晶粒尺寸的影响
Effect of Ce on Grain Size of High-purity Mg-3Al Alloy
摘要
Abstract
The effect of Ce on the grain size of a high-purity Mg-3Al alloy was investigated. The results showed that the grain size of high-purity Mg-3Al alloys increases with increasing Ce addition.When the Ce content was 1％, the grain size reached 870 μm. The Ce reacted preferentially with Al to form Al11 Ce3 phase, and it was considered that the Al11 Ce3 phase could not act as nuclei because it was distributed mainly at inter dendritic region. The reaction between Al and C led to degradation of nucleation potency, which was the main cause of grain coarsening.关键词
