This work demonstrates the possibility to apply T5 and T6 heat treatments to EN AC-46500 aluminium components conformed by Semi-Solid Rheocasting (SSR). The study of temperature and time effect in annealing, tempering and artificial aging conditions has permitted to optimize the component mechanical properties. The experimentation has been accomplished by means of hardness Brinell tests, tensile tests, optic and electronic microscopy. The mechanical properties obtained in SSR components, reach analogous values to the ones obtained by die cast components and submitted to the same heat treatments.
