— The high temperature low‐cycle fatigue behaviour of two turbine disc alloys was studied at 600 and 650°C, at total strain ranges, between 0·6 and 2·1%. These results showed that the life of both alloys may be predicted by a Coffin‐Manson type equation. The fracture surfaces of the specimens were examined by scanning electron microscopy.
