在20世纪80年代开发了用于聚变应用的低活化钢，以取代最初考虑的高温商业钢。新钢在商业钢之后图案化，目的是新钢在夏比试验中具有与它们所取代的钢相当或更好的屈服应力和极限拉伸强度和冲击韧性。日本、欧洲和美国开发的低活化钢实现了这一目标。尽管低活化钢的拉伸和冲击韧性超过了它们被图案化后的商业钢，但它们的蠕变断裂性能不如它们所取代的一些商业钢。它们比20世纪80年代以来开发的商用钢更差。在本文中，减少激活钢和新的商业钢之间的成分差异进行了检查，并提出了新的和改进的减少激活钢的开发组合物。由爱思唯尔公司出版
Reduced-activation steels for fusion applications were developed in the 1980s to replace the elevated-temperature commercial steels first considered. The new steels were patterned after the commercial steels, with the objective that the new steels have yield stress and ultimate tensile strength and impact toughness in a Charpy test comparable to or better than the steels they replaced. That objective was achieved in reduced-activation steels developed in Japan, Europe, and the United States. Although tensile and impact toughness of the reduced-activation steels exceed those of the commercial steels they were patterned after, their creep-rupture properties are inferior to some commercial steels they replaced. They are even more inferior to commercial steels developed since the 1980s. In this paper, compositional differences between reduced-activation steels and new commercial steels are examined, and compositions are proposed for development of new-and-improved reduced-activation steels.
