AbstractAbstractThe hot ductility behaviour of high-purity iron-base alloys was determined by hot tensile tests. The observed ductility trough in the 850–1100°C temperature range was found to be a product of the interaction between the hardening effect of AIN precipitates and the intergranular segregation of sulphur. The dissolution of AIN leads to an improvement in hot ductility and the temperature for complete dissolution of AIN coincides with the onset of dynamic recrystallization.MST/171
