Texture induced grain coarsening in severe plastic deformed low carbon steel

Abstract : A low carbon steel sheet was deformed by equal-channel angular pressing with an intersection angle of the die channels of 130 degrees for four passes, via route A. Using electron backscatter diffraction, a significant increase in the grain size was observed during testing. This could be explained by the coalescence of neighboring initial grains due to the evolution of the crystallographic texture. Polycrystal simulations could also reproduce the coarsening tendency, together with the evolution of the disorientation distribution.
