摘　　要：介绍了含铌新型锆合金氧化动力学曲线的特点及氧化膜结构方面的研究成果,并与Zr-4合金进行了对比,在此基础上归纳分析了锆合金氧化物t→m转变和晶粒转变(柱状→等轴状)的特点、内在关系及发生的可能原因,指出了含铌锆合金中沉淀物的种类以及其对锆合金氧化膜的影响。Compared with Zr-4 alloy, the characteristics of oxide dynamics curve for zirconium alloys containing Nb and the status of research on the structure of oxide film are introduced. On the basis of these, the characteristics of the t→m change and grain change（columnar→equiaxed）, as well as intrinsic relationship between the two and the possible reasons for changes, are summed up and analysed. At last, the type of precipitates in the new zirconium alloys and their effects on the oxide film are also reported.
