Deformation behaviour of low carbon deep-drawing steels influenced by phase transformation

The aim was to determine the phase transformations temperatures of a specific IF steel grade, microalloyed by titanium, and quantify influence of phase composition on its deformation resistance in comparison with a common low carbon deep-drawing steel grade. In the case of the IF steel separate, sufficiently accurate, models describing mean equivalent stress after heating of the material directly to the forming temperature, matter for three temperature regions (ferrite, ferrite + austenite, or austenite), were developed.
