设计了改进成分的中国低活化马氏体钢（CLAM），测定了其拉伸性能、韧脆转变温度（DBTT 41 J）、蠕变性能和热物理性能。在HT-7托卡马克装置上进行了CLAM与等离子体的相互作用实验，计算了CLAM的活度、余热和γ剂量率随冷却时间（CT）的变化，得到了CLAM中杂质的控制水平。在700°C和740°C下用CVD法在CLAM钢上制备的绝缘涂层为纯Al_2O_3和Al_2O_3，表面有约1μm厚的氧缺陷层。涂层表面电阻率达到104Ω m2左右。
Chinese low activation martensitic steel (CLAM) has been designed with improved composition, and its performance, such as tensile properties, ductile–brittle transition temperature (DBTT41J), creep and thermal physical properties, has been determined. The interaction experiments between CLAM and plasma were carried out in the HT-7 tokamak facility and the activities, afterheat and gamma dose rate for CLAM as a function of cooling time (CT) were calculated to obtain the required control levels of impurities in CLAM. The insulator coatings on CLAM steel prepared by the CVD process at 700°C and 740°C have pure Al2O3and Al2O3with an oxygen deficiency layer on surface about 1μm thick. The electrical resistivity of the coating reaches about 104Ωm2on the surface.
