Fatigue Crack Growth Resistance of Special Nodular Cast Irons

Abstract:

Article Preview

The strength and fatigue crack growth resistance (FCGR) of ferritic, pearlitic and austenitic nodular cast irons (NCIs), recommended to be used in structural components working at low (up to –60 °C), cryogenic (below –60 °C) and elevated (450 °C) temperatures, are analysed. The influence of the manganese content and the strain-induced martensite transformation on FCGR of the austenitic NCIs is shown. An admissible phosphorus content for the optimum wear resistance and FCGR is determined. The strength and FCGR of the NCIs and corresponding rolled steels are compared.
