| Research Abstract |
The 9CrODS ferritic steel is a oxide dispersion strengthened composite materials containing residual ferrite as a hard phase. It was shown that a formation of the residual ferrite is attributed to pinning effect of α/γ interface by oxide particles and that its hardening is also attributed to nano-size oxide particle distribution keeping coherency. Through hot-rolling processing, the high-temperature strength and ductility were adequately improved by inducing ferrite transformation for a part of martensitic phase. Production process of the advanced ODS composite material was newly proposed.
