主 题：reduced activation steel consumable electrode remelting microstructure creep fracture
摘 要：The effect of smelting processes on mechanical properties and microstructure of reduced activation ferritic steels was *** properties and impact toughness of reduced activation ferritic steels were obviously improved by vacuum induction melting followed by consumable electrode remelting process in comparison with the conventional vacuum induction melting *** difference of impact toughness and creep properties between both steels mainly depended on the aspect ratio and mean size of *** the aspect ratio of carbides makes development of a shear band more difficult , which could increase impact energy and creep resistance.
