Abstract

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

Keywords

grey cast iron; ductile cast iron; quasistatic nanoindentatio; nanohardness; reduced young modulus
