Heat treatment led to spheroidization of eutectic Si, gradual disintegration, shortening and thinning of Fe-rich intermetallic phases, the dissolution of Cu-rich phases and the precipitation of finer hardening phase (Al2Cu). The change of morphology of structural components significantly affects the fracture surface of Al-alloy. The fracture morphology changes gradually from dominant brittle transcrystalline cleavage fracture to ductile fracture with numerous small dimples (locally presence the cleavage fractures of Fe-rich phases).}, number={2}, journal={Periodica Polytechnica Transportation Engineering}, author={Hurtalová, Lenka and Tillová, Eva and Chalupová, Mária}, year={2013}, pages={117–122} }
