✦ Synopsis

Cast iron with bainitic matrix and globular graphite, so called austempered ductile iron (ADI), allows the substitution of heat‐treatable steels. The use of ADI in safety‐relevant components requires knowledge of the fracture and fatigue behaviour. Cyclic stress strain behaviour and fatigue life at total strain control and random loading have been investigated at ADI (EN‐GJS‐1000‐5) and pearlitic cast iron (EN‐GJS‐600‐3). In addition fracture mechanic tests at cyclic loading at various stress ratios were carried out.
