In-situ neutron diffraction techniques made clear that the misfit strains between grains accompanied with the grain-scaled internal stress (intergranular stress). In the dual phase steel, the intergranular stress was superposed on phase stress. Both long-range internal stress and short-range one like forest dislocation hardening may cause the resistance for dislocation motion in the steels.}, pages = {9--14}, title = {In-situ neutron diffraction study on work-hardening behavior in a ferrite-martensite dual phase steel}, volume = {19}, year = {2011} }
