摘要：

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