X-ray diffraction Fourier profile analysis has been performed for polycrystalline α-brass plate with 31.55 wt-% Zn after a series of uniaxial tensile tests with different strain rates. Dislocation density p and configuration parameter M may be presented as a function of ap- plied stress σ_a.A mechanism of alternative long-range and short-range strain hardening has been proposed.
