具有贝氏体基体和球状石墨的铸铁，即所谓的等温淬火球墨铸铁 (ADI)，可以替代热处理钢。在安全相关组件中使用 ADI 需要了解断裂和疲劳行为。已在 ADI (EN-GJS-1000-5) 和珠光体铸铁 (EN-GJS-600-3) 上研究了总应变控制和随机载荷下的循环应力应变行为和疲劳寿命。此外，还进行了不同应力比下循环载荷下的断裂力学测试。
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.
