| 中文摘要 | 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 + ESR, CS350 steel) had been studied. The results indicated that the steels showed similar values of hardness and tensile strength, however, creep properties of CLF-1 steel were obviously improved by VIM + ESR process. M(23)C(6) and M(7)C(3) Carbides were precipitated in the CS25 steel, and M(23)C(6) carbides were precipitated in CS350 steel after high-temperature tempering at 1013 K for 90 min. Creep properties of CS25 steel were shown to be dramatically deteriorated by the existence of rod M(7)C(3) precipitates, which was due to W macrosegregation in the CS25 steel melted by VIM. M(7)C(3) was replaced by M(23)C(6) after ageing at 823 K for 5000 h. (C) 2010 Elsevier B.V. All rights reserved. |
