...) technique to observe the influence of grain refinement on mechanical and damping properties. Electron backscattered diffraction (EBSD) analysis were conducted for detailed and deep understanding of possible mechanism and microstructure at longitudinal cross sections of the samples. Further, the room...

..., it is shown that, with this device, stage IV may be reached and analyzed on polycrystals as well as on single crystals. The second part is devoted to equal channel angular extrusion, which is known to promote grain refinement after several passes. A direct comparison of the crystallographic textures measured...

... to grain refinement, with the average grain size decreasing with temperature. Moreover, a steady state grain aspect ratio and inclination of the grain long axis with respect to the shear plane is observed. With increasing shear strain, the fraction of low angle grain boundaries goes over a maximum...

... ¯ ) [ 111 ] and D 2 ( 1 ¯ 1 ¯ 2 ) [ 1 1 1 ] components dominates (the former in the case of positive shear or clockwise rotation about the r -axis, and the latter during negative shear). The tendency toward a single end orientation imposes certain limitations on grain refinement, as this would ultimately...
