dc.description.abstract | The effects of tungsten addition on the microstructure and high-temperature tensile strength of 9Cr-Mo steels have been investigated by using three different steels: M10 (9Cr-1Mo), W18 (9Cr-0.5Mo-1.8W), and W27 (9Cr-0.1Mo-2.7W) steels. The tungsten-added 9Cr steels have revealed better high-temperature tensile strength. Microchemical analysis for (Cr,Fe)(2) (C,N) revealed that the tungsten addition increased the Cr/Fe ratio, which resulted in the lattice expansion of (Cr,Fe)(2) (C,N), and then the enhanced pinning effect on the glide of dislocation. In addition, in M10 steel, the M23C6 carbides quickly grew and agglomerated, while the tungsten-added 9Cr steels revealed a fine and uniform distribution of M23C6 carbides. Dislocation recovery during tempering treatments was delayed in tungsten-added 9Cr steels, which was correlated with the stabilized precipitates and the decreased self-diffusivity of iron. It is, thus, believed that the excellent high-temperature tensile strength of tungsten-added 9Cr steels is attributed to the stabilized M2X carbo-nitrides and M23C6 carbides and the decreased self-diffusivity of iron.
