Fatigue crack propagation properties of Austempered Ductile Iron (ADI) and Perferritic Isothermed Ductile Iron (IDI®) are evaluated in this article. ADI represents the top strength material of the ductile iron (DI) family. IDI® is defined as an intermediate grade between the low hardness grades of ADI and pearlitic DI. Generally, both DI’s are intended to be used for castings subjected to variable dynamic loading during their service, where familiarity with fatigue properties has the great importance. Fatigue crack propagation curves da/dN vs. Ka and the threshold amplitude of stress intensity factors Kath for ADI and IDI® are presented here.

Abstract
Fatigue crack propagation properties of Austempered Ductile Iron (ADI) and Perferritic Isothermed Ductile Iron (IDI®) are evaluated in this article. ADI represents the top strength material of the ductile iron (DI) family. IDI® is defined as an intermediate grade between the low hardness grades of ADI and pearlitic DI. Generally, both DI’s are intended to be used for castings subjected to variable dynamic loading during their service, where familiarity with fatigue properties has the great importance. Fatigue crack propagation curves da/dN vs. Ka and the threshold amplitude of stress intensity factors Kath for ADI and IDI® are presented here.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
