摘　　要：对中国低活化马氏体钢———CLAM钢的冲击和拉伸性能进行了测试。结果表明:CLAM钢的塑-脆转变温度在-100℃左右,低于国际上其它几种典型的低活化马氏体钢;在室温和600℃时抗拉强度分别为668和334 MPa,类似于EUROFER97的性能。约8μm的晶粒尺寸是CLAM钢具有较好冲击和拉伸性能的主要原因之一。The impact and tensile tests were carried out on the China Low Activation Martensitic steels （CLAM）. The results show： the Ductile-Brittle Transition Temperature （DBTY） is about - 100 ℃, which is lower than those of some other RAFMs; The ultimate strength are 668 MPa at room temperature and 334 MPa at 600℃, which are comparable to those of EUROFER97. The finer grain size of about 8 μm was considered as one of reasons for the superior mechanical properties of CLAM.
