Abstract
A Na-modified, as-cast Al-7 wt% Si alloy was processed by equal channel angular pressing (ECAP) up to 8 passes by route A at ambient temperature using a 90 degree square section die, obtaining improved strength ductility and work fracture. From the first pass, porosity is removed, the eutectic constituent is refined and the eutectic silicon particles are partially redistributed...
