摘要
利用示差扫描量热仪（ＤＳＣ）分析方法，研究了快凝ＡｌＦｅ（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。
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 Jeziornys mathematical model. Therefore, the internal relations between kinetic parameters and microstructures of materials have been built up.
