摘　　要：了解锆合金塑性变形行为,为M5合金的工程应用提供数据.试验采用静态拉伸试验方法对国产及法国产M5锆合金核燃料包壳管在室温和400℃下的拉伸性能进行了研究.结果表明,国产及法国产M5合金的拉伸性能无显著差异.在均匀塑性变形阶段,室温拉伸时法国产M5的形变硬化指数稍高于国产M5,400℃拉伸时两种材料的均匀塑性变形阶段均分为两个阶段,前均匀塑性变形阶段(n1)和后均匀塑性变形阶段(n2),法国产M5的n1明显高于国产M5的n1,法国产M5的n2稍高于国产M5的n2.In order to study the plastic deformation behavior of zirconium alloys to provide data for engineering applications,the tensile properties of domestic and France-made M5 zirconium alloy nuclear fuel cladding tubes were studied by means of static tensile test at room temperature and 400℃. The results show that the tensile properties of domestic and France-made M5 have no significant differences. In the uniform plastic deformation stage, when tensile deformation happens at room temperature, the hardening exponent of France made M5 is slightly higher than that of domestic M5. When the two kinds of materials are tensely deformed at 400℃ , the uniform plastic deformation stage consists of two stages, namely pre-uniform plastic deformation stage（n1） and n1 of France-made M5 is significantly higher than that higher than that of domestic M5. post-uniform plastic deformation stage（n2）. The of domestic M5, n2 of France＇-made M5 is slightly
