Microstructure investigation of cast irons with nodular and flake graphite via nanoindentation



The paper investigates and compares local mechanical properties of misstructure components found in grey cast iron EN GJL-300 iron and ductile iron EN GJS-500-7. The microstructure of both cast irons are analyzed by LOM and then particular detected microstructural component and their local mechanical properties are investigated. Finally, resulting nanohardness and reduced Young modulus of the components are discussed and compared between the two used cast irons. Hysitron TI-950 measuring device equipped with Triboscan software is used to perform experiment measurements.
