摘要：
Effects of combined additions of tungsten and molybdenum on the creep properties of Fe3AI-based alloys have been investigated. Results show that combined additions of tungsten and molybdenum increase significantly the creep rupture life of the Fe3Al base alloys at high temperature. TEM analysis of the alloys containing tungsten plus molybdenum indicates that both solid-solution strengthening and precipitation harden- ing make the significant increase of creep rupture life.
