Abstract

In the present work it has been studied the microstructure and the mechanical behaviour of a material produced by rheocasting, a new semisolid industrial process which introduces important improvements in comparison to conventional routes. The microstructure of the A357 hypoeutectic Al-Si alloys has been analysed before and after material injection. In both cases the microstructure was fine and homogeneous. Tensile tests have been done with specimens machined from real rheocasted components in two conditions, without any heat treatment and after T5 heat treatment. The results were found to be better than those obtained for this alloy when produced by conventional means.
