Tensile test was performed in order to investigate the effects of precipitates and solute Mg concentration on the tensile properties and serration of Al–5% and –10% Mg binary alloys aged at temperatures between 373 and 573 K. The obtained results are as follows: (1) The yield stresses of 10% Mg alloys aged at about 453 K increased due to the formation of a rod-like precipitate at the early stage of aging. (2) The elongation to fracture decreased with the precipitation of both particle-like and rod-like precipitates. (3) The strain, stress and maximum stress drop at the serration, were varied in relation to the flow stress affected by the formation of precipitates and the change in solute Mg concentration in the matrix.
