Microstructure and local crystallography of rolled Al–1wt%Mn single crystals of {001}〈110〉 orientation

Al–1wt%Mn single crystals of {001}〈110〉 orientation have been rolled to 30 and 50% reductions under controlled homogeneous rolling conditions. The local orientations have been measured by the electron back-scattered pattern (EBSP) technique and a semi-automatic TEM method over different scales. EBSP orientation image maps (OIMs) based on the local orientation data and TEM micrographs were used to reveal the deformation structure. It was found that the crystals subdivided into different macroscopic regions across the specimen thickness and significant microstructural difference was observed in regions with different macroscopic orientations. Good agreement was revealed by comparison of the results concerning microstructure and local crystallography obtained from EBSP and TEM measurement.
