Resumo
This study is about the effect of an annealing at 600ºC on the grain size and texture of a hot band. This hot band was, further, cold rolled (from 2.5 mm to 0.5 mm) followed by a continuous annealing at 780ºC. The texture was determined for those two conditions with the Inverse Pole Figure Method. The AR1 e AR3 points were found by dilatometry. For this steel, 2h (a 600ºC) was enough for attaining grain size > 70 µm. However, a time greater than 10 h is necessary for producing grain size larger than 100 µm. The change of texture observed for time of annealing larger than 6h can be associated to the disappearing of small grains (with size ~10 microns) that were found in the samples with annealing time lower than 6h. The intensity of {110} planes decreases after the cold rolling and continuous annealing. Grain growth favors the increase of {111}, however larger time of heat treatment seem favor na increase of {110} planes, while {111} planes decrease.
