国际上低活化钢的研究工作已取得重大进展。已对未辐照和辐照条件下的广泛拉伸、断裂韧性、疲劳和蠕变性能进行了测试和评估。由于不可能将所有工作纳入本次有限审查，因此将介绍选定的领域以表明最近国际努力的范围和进展。其中包括 (1) 机械性能研究的结果，这些结果已合并到数据库中，以确定 ITER 包层模块初步设计的材料设计限制。 (2) 结果表明，嬗变产生的氦对断裂韧性的影响比之前指出的要小。 (3)进一步努力减少辐照引起的断裂韧性退化。 (4)引入塑性变形的辐照后本构方程。 (5)用于提高高温强度的ODS钢的生产。 (6)开发了提高ODS钢断裂韧性的方法。
Significant progress has been achieved in the international research effort on reduced-activation steels. Extensive tensile, fracture toughness, fatigue, and creep properties in unirradiated and irradiated conditions have been performed and evaluated. Since it is not possible to include all work in this limited review, selected areas will be presented to indicate the scope and progress of recent international efforts. These include (1) results from mechanical properties studies that have been combined in databases to determine materials design limits for the preliminary design of an ITER blanket module. (2) Results indicate that the effect of transmutation-produced helium on fracture toughness is smaller than indicated previously. (3) Further efforts to reduce irradiation-induced degradation of fracture toughness. (4) The introduction of a post-irradiation constitutive equation for plastic deformation. (5) The production of ODS steels that have been used to improve high-temperature strength. (6) The method developed to improve fracture toughness of ODS steels.
