Abstract :
The dependence of the strain hardening rate on the size and shape of the Si particles, dendrite arm spacing and Mg content has been studied using monotonie tensile testing and Bauschinger effect. At low strains, the hardening rate is higher for material with elongated Si particles and higher Mg content. At large strains, the hardening rate is higher for material with small dendrites. The internal stresses increase rapidly at small strains, saturating at large strains. The saturation value is higher for material with elongated Si particles, small dendrites or higher Mg content.
