Martensitic steels containing carbon are characterized by their high tensile strength and the solid solution strengthening by super saturated carbon has been believed to be the dominant strengthening mechanisms. In this study, X-ray diffraction analysis revealed that the lattice structure of as quenched martensite is not bct but bcc independent of carbon content in the carbon concentration range below 0.5% at least. In addition, a theoretical analysis on the strengthening mechanism indicated the fact that the strength of as quenched martensite can be reasonably explained by the particle dispersion strengthening based on the particle cutting model. As a result, it was confirmed that auto-tempering cannot be avoided in conventional martensitic steels under the engineering cooling condition.
