In this investigation, the authors tried to improve the elevated temperature properties, in particular, creep rupture strength of the fully ferritic steel by employing the technique of dispersion strengthening. As a result, it was found that the sintered alloy steels with dispersed fine T-A12O3 particle, especially those obtained by the technique of the liquid phase sintering and the hot-working after sintering, have higher creep rupture strength than those of the wrougth steels having nearly the same compositions, and that these dispersion strengthened steels are promising as a new type of heat resisting material.
