摘要
采用机械合金化附加后续的热处理工艺,制备了2个系列不同组分的Al-Cu-Fe合金粉末,使用X射线衍射(XRD)结构分析技术研究一定的球磨时间及退火条件下粉末组分对准晶形成的影响.研究结果表明,Al-Cu-Fe二十面体准晶的形成对原始混合粉末的组分很敏感,在相同的球磨时间及退火条件下,Al70Cu20Fe10是形成准晶的最佳组分.
Two kinds of Al-Cu-Fe alloying powder were prepared by mechanical alloying and a later heat treatment process. The effects of powder composition under certain ball milling time and annealing condition were studied using the structure analysis method based on X-ray diffraction. The experimental results show that the formability of Al-Cu-Fe icosahedral quasicrystalline phase is sensitive to the composition of the powders, and the optimal composition is under given ball milling time and annealing condition is A170Cu20Fe10.
