摘要
汽轮机高温螺栓材料Ｒ２６合金由于膨胀系数大和抗应力腐蚀性能差已被替代。作者论述了高温螺栓Ｒ２６合金替代材料的选择和材料负蠕变及其影响。
Abstract In this paper, the high temperature bolt material for steam turbine——alloy R26 has already been replaced because of its excessively big coefficient of expansion and its bad stress corrosion resistance. The author expounds also the choice of the replacing material for high temperature bolt alloy R26, the material negative creep and its influence. Figs 4, tables 3 and refs 4.
