Resumo
Compression tests of sintered (Al–12Si)–xSn composites have been carried out and it has been found that the flow curves of these composites consist of up to eight alternating linear and parabolic deformation stages. The strain-hardening coefficient θi of the material at each stage is constant. With increasing the order number of the stage i, θi decreases and can take a negative value. In the general case, θ = \(\theta _{i}^{n},\) where n = 1 at the linear flow stage and n = 0.5 at the parabolic (odd) stage.
