Fig. 3. Mechanical behaviors of the series dual-phase alloy.
a Engineering compressive stress-strain of the series dual-phase alloys. The error bars represent the standard deviation. b Neutron diffraction profiles at different strains (ε) along the loading direction (LD). The intensities of (531)L and (422)L peaks are magnified five times for a clear view. c lattice strain of the S-3 alloy along loading direction (LD). The error bars represent the standard deviation. d Macroscopic stress-strain compared with specific stress partitioning in α phase and L phase. Note that the strain is determined by in-situ neutron diffraction without an extensometer. e Dynamic dislocation densities (ρα) of the α phase determined by modified Williamson-Hall (MWH) method. The error bars represent the standard deviation.
