- Abstract
By means of diffraction using transmission electron microscopy, the role of stacking fault energy during active plastic deformation of polycrystalline specimens of Cu–Al and Cu–Mn alloys in the low-stability states is revealed. For this purpose, the dislocation and dislocation-disclination substructures in the solid solutions of Cu–Al and Cu–Mn fcc-alloys with the grain sizes within 20–240 subjected to tensile deformation are studied in the concentration ranges of 0.5–14 at.% Al and 0.4–25at.% Mn. An interrelationship between the parameters characterizing the defect substructure and the stacking fault energy is established. The curves of this dependence are compared for different structural-phase states of the alloys. The dislocation substructure (DSS) types of both alloy systems are found to be similar. The only difference is the absence of micro-twinning in Cu– Mn alloys, observed in Cu–Al alloys. The influence of the stacking fault energy on the DSS formation and parameters is analyzed.
