dc.description.abstract | The tensile properties and inhomogeneous deformation of coarse ferrite-martensite dual-phase steels containing 17-50% martensite were analysed. The stress of dual-phase steels at equal strain increased with increasing volume fraction of martensite, f but the rate of increase was reduced after f = 0.3. The strain hardening rate was dependent on f at small strains (epsilon less-than-or-equal-to 0.03), however, it became independent of f at larger strains. It was found that the deformation of the dual-phase steels divided into three different stages when f was less than about 0.3. The concurrent in situ stress-strain states of ferrite, martensite and their composite, and the stress ratios and strain ratios between ferrite and martensite were evaluated by means of a new stress and strain partition theory. The martensite phase deformed plastically after the uniform strain for f < 0.25, while it was plastic before the uniform strain for f > 0.25. The theoretical analyses for inhomogeneous deformation implied that the volume-fraction dependence of the stress and the characteristics of the strain-hardening rate were influenced by the plastic deformation of martensite. Further, the in situ stress-strain curves of ferrite and martensite and the internal stresses at respective phases were calculated from the partitioned stresses and strains. | - |
