The effect of iron on the precipitation of a technical Al‐Mg‐Si alloy was studied by macroand microhardness, Y‐modulus and SANS with DKD and was compared with a pure alloy. The iron phases of the technical alloy were preferentially considered by the SANS. In addition the damping by the elastomat of FÖRSTER and the variance of the microhardness were measured. It was found that iron essentially influences the kinetics of the precipitate, particularly the mechanism of nucleation and precipitation sequence.
