Abstract
In this paper a self-hardening Al-based alloys (AlZn10Si8Mg) with potential application in automotive industry have been proposed.
Samples produced with different solidification rate have been considered. Mechanical strength, hardness evolution, morphological behaviour and corrosion resistance of the prepared samples with different content of Mg (in the range of 0.5÷3 wt%) have been investigated. Fracture surface analysis has been carried out to identify the presence of defects on the fractured surface and finally to correlate them to the mechanical performances.
As expected, higher solidification rate favours the development of the finest microstructure connected to good mechanical performances. A uniform distribution of a very fine Zn-based intermetallic phase, responsible of the self-hardening feature of the alloy was detected.
Addition of Mg up to 1% contribute to enhance the alloy mechanical performances and its resistance to the corrosive media.
