Acesso em:.https://repositorio.ufpa.br/handle/2011/9811Previous results in Aluminum have show that the Critical Resolved Shear Stress is not the same for different slip system when flat single crystals are deformed. This is consequence either different stress is necessary to move edge screw dislocation or surface effect (aluminum have a oxide layer attached). In the present work similar analysis have been done in copper. Flat single crystals of special orientation have beem grown Under inert atmosphere in a graphite mould. The slip system is determined by following the tensile orientation with this purpose a deformation frame is attached to the X-Rays difractomer and movement of the tensile axis is measured by using the LAUE technique. It is found similar results than in aluminum which means that differences in flow stress are mainly tested to dislocations.Acesso AbertoDeformações (Mecânica)Deslocamentos em cristaisCobreDissertaçãoCNPQ::CIENCIAS EXATAS E DA TERRA::FISICA::FISICA DA MATERIA CONDENSADA::PROPRIEDADES MECANICAS E ACUSTICAS DA MATERIA CONDENSADA
