Due to the heat treatment T5, there isn´t significant change in the morphology of the intermetallic phases Mg2Si and Al2Cu, which is beneficial for the resulting mechanical properties of the castings. Further, spheroidization of eutectic silicon is not noted. In general, precipitation hardening of Al-Si based alloys, due to the presence of intermetallic phase Mg2Si and Al2Cu is a result of heat treatment T6. The morphology of Fe-rich phases is not changed by T6. The possitive effect of heat treatment on the morphology of Fe-rich phases is recorded with the simultaneous effect of additive elements such as Mn, Zr, Co. The ability to predict intermetallic phases is important in terms of determining the resulting mechanical properties of Al-Si-Cu-Mg castings. ----------------------------------------------------------------------------------------------------- Vplyv zmeny stratégie na riadenie podnikových procesov This article focuses on the impact of a strategy change on the business process management of a manufacturing company.
