Influence of smelting processes on precipitation behaviors and mechanical properties of low activation ferrite steels
▶ Creep properties could be improved dramatically by control of smelting process. ▶ VIM + ESR smelting process could improve the W macrosegregation. ▶ W could accelerate the transition of M 7C 3 to M 23C 6 in RAFM steel. ▶ The synergetic effect of carbides and tungsten depletion of solid solution le...

In this paper, the influence of smelting processes on precipitation behaviors and mechanical properties of CLF-1 (China low activation ferrite) steel was investigated. Mechanical properties of CLF-1 steels melted by vacuum induction melting (VIM, CS25 steel) and vacuum induction melting followed by consumable electrode remelting (VIM
