Thermo-mechanical processing of low manganese, titanium added pipeline steels

Thermo-mechanical processing of a new family of low carbon, low manganese, titanium added steels was studied under a variety of simulated conditions. In this paper emphasis is placed on developing a better understanding of the effect of Ti and N on the microstructural development and mechanical properties of these new steel types. Also, the behavior of precipitates during hot deformation was examined. The results indicated that steel with a Ti/N ratio lower than the stoichiometric value provide best mechanical properties.
