摘要
利用示差扫描量热卡计(DSC),结合X射线衍射分析(XRD)及透射电子显微镜分析(TEM)等实验,研究了部分非晶态Fe33Zr67合金条带的晶化动力学结果表明:晶化过程为晶粒长大过程所控制,尽管在条带中淬态核分布明显不均匀,与经典Avrami分析的基本假设相矛盾,但该晶化过程仍然与JMA反应动力学结论一致.
Differential scanning calorimeter(DSC), X-ray diffractometer(XRD) and transmition electron microscopy (TEM) were used to study the crystallization kinetics of partially amorphous Fe33Zr67 alloys. Results show that the grain growth dominated the crystallization process. Although an inhomogeneous distribution of quenched-in nuclei exists in the samples. which is contrary to the basic assumptions of the classical Avrami analysis, the obtained Avrami exponents are still in agreement with the Johnson-Mehl-Avrami (JMA)analysis.
