摘要

Using transmission electron microscopy, the paper investigates the structure and strength properties of polycrystalline alloys based on the Cu-Al system with mesoscopic grains. The analysis of the mechanical behavior is based on quantitative parameters of the grain and dislocation structures and long-range stresses. Strain hardening mechanisms are discussed herein, involving the experimental data on the evolution of deformed grain and defect structures.
