摘 要: 利用示差扫描量热仪(DSC)分析方法，研究了快凝 Al-Fe-(Cr，Mo)-Si合金中准晶相的转变动力学特征。结果表明：采用Jeziorny 数学模型对准晶相的转变非等温DSC曲线进行分析，其转变动力学特征参数表征的物理意义与透射电镜(TEM)的分析结果基本一致。因此，建立了宏观分析与微观显微组织之间的内在联系。

Abstract:Differential Scanning Calorimetry (DSC) was used to study kinetic charateristics of transformation on quasicrystalline phases in a rapidly solidified Al-Fe-(Cr, Mo)-Si alloy. It is shown that the description of kinetic parameters on transformation of quasicrystalline phases is basically consistent with the results of TEM analysis, by analysing the non-isothermal DSC curves of quasicrystalline phases transformation by Jeziorny's mathematical model. Therefore, the internal relations between kinetic parameters and microstructures of materials have been built up.
Key words: rapid solidification quasicrystalline phase DSC kinetics of transformation
