  • Systematic investigation on mechanism of texture development in deep drawing steels related to effects of interstitial content, hot rolling and primary recrystallization conditions


For the investigations at MPI a series of 50 kg-melts with 0.0006 to 0.1 wt % C and additions of Mn, Si, Ti, N and Al were used. After hot rolling in the austenite range by a heat treatment the grain size of ferrite and the precipitation of carbides were adjusted to desired values. The material was cold rolled by 70 %. Besides the texture measurements by X-rays, single orientations were measured. CSM has drawn its attention to the texture development control in deep drawing steels from the point of view of both industrial applications and understanding of the metallurgical mechanisms responsible for the microstructural and textural evolution during the different steps of steel production. The studied materials were three aluminum killed drawing steels in which the only difference was the carbon content, and a controlled low amount of other interstitial solutes. These compositional differences and low hot rolling finishing temperatures have been investigated in terms of microstructural and mechanical properties up to the cold rolled - continuously annealed products. The role of carbon during the cold deformation has been deduced from experiments. Finally the primary recrystallization processes have been investigated from a kinetic point of view and the metallurgical aspects connected to the development of the main textural components have been discussed. With the aid of a mathematical model developed during this research activity, the competition between recovery and recrystallization during isothermal annealing at low temperature has been studied.
