摘 要: 利用示差掃描量熱儀(DSC)分析方法，研究了快凝 Al-Fe-(Cr，Mo)-Si合金中準晶相的轉(zhuǎn)變動力學(xué)特征。結(jié)果表明：采用Jeziorny 數(shù)學(xué)模型對準晶相的轉(zhuǎn)變非等溫DSC曲線進行分析，其轉(zhuǎn)變動力學(xué)特征參數(shù)表征的物理意義與透射電鏡(TEM)的分析結(jié)果基本一致。因此，建立了宏觀分析與微觀顯微組織之間的內(nèi)在聯(lián)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
