The modeling of the deformation behavior of Cu–Al–Nb–X shape memory alloys containing primary particles

The modified model of the continuum mechanics approach based on the effective medium approximations and supplemented by the dislocation plasticity model enabled analysis of the deformation course of the Cu–Al–Nb–X (where X = Ni, Co, Cr or Ti) alloys. By comparing the simulated and experimental stress–strain curves for these alloys, the effect of particle size, volume fraction and their elastic properties on the deformation response is analysed.
