Résumé:Title screen
The local curvature and torsion (χ) of the crystal lattice formed during the deformation of polycrystalline FCC solid solutions is studied via transmission electron microscopy (TEM). Polycrystalline alloys of Cu and Al (Al contents of 0.5 and 14 at %) with mean grain sizes of 10 to 240 µm are considered. It is established that the sources of curvature and torsion are boundary intersections, grain boundaries, and misoriented dislocation and disclination substructures that form during deformation of the alloys. The greatest curvature and torsion of the crystal lattice are due to grain boundaries and boundary intersections. The effect of grain size has on the value of χ is determined.
