Sažetak
Novel multicomponent AlSi9MgMn alloy has been investigated due to unusual chemical composition. An AlSi9MgMn alloy is the first aluminum alloy with low iron and intentionally high manganese content developed for structural automotive casting produced by high pressure die casting process. This alloy has been characterized by enhanced mechanical properties of castings such as ductility and toughness at high cooling rates due to evolution of intermetallic AlxMnyFezSiu phase in globular manner. Characterization of novel multicomponent AlSi9MgMn alloy at low cooling rate indicates evolution of same intermetallic phases in different morphology which directly influence on development of mechanical properties. Investigation revealed evolution of of characteristic microstructural constituents on the base of their morphology and chamical composition: primary aluminum (aAl), complex intermetallic phase AlxMny, FezSiu, unfavorable blocky Al5FeSi, main eutectic (aAl + bSi), low temperature complex Al8Mg3FeSi6 phase and secondary eutectic phase Mg2Si. Different morphology related to low cooling rate induced lower values of mechanical properties. Characterization of novel multicomponent AlSi9MgMn alloy indicates applicability of this material for certain automotive industry cast at low cooling rates.
