Microtexture and Orientation Relations Analysis in Surroundings of Shear Bands in Monocrystalline Copper

By means of systematic measurements of single orientations the microtexture and the orientation relations in the area of partly recrystallized shear bands in deformed (112)[111̅] single crystals of pure copper have been investigated. In the analysis the distribution function of orientations and orientation differences of various kinds were calculated. In the calculations of these orientation characteristics the direct method and also for comparison the commonly used series expansion method were applied. To enable a comparison of the calculated results, both methods require some definite modifications which are explained in the paper. The results of the microtexture analysis are discussed concerning details of the texture changes and the orientation relations between the deformed matrix and the recrystallized grains.
