In situ analysis of deformation mechanisms of Cu-based fee materials under uniaxial loading

摘要

By associating texture determinations and strains measurements by neutron diffraction, the elastoplastic behaviours of families of crystallites with the same crystallographic orientations were characterized in situ in a brass and a bronze alloys under uniaxial loading. The polycrystalline orientation analysis method proposed here allows an intermediate approach between a "local" (intragranular) and a "global" characterization, within the bulk of massive samples.
