Creating a scientific approach to the ductility of metal alloys, which is determined by
mechanical tests. Develop a method for determining the physical plasticity of materials δ * in
depending on the degree of deformation ε in standard mechanical tensile and compressive tests, and
also develop a technique for constructing deformation curves δ * = f (ε) in addition to standard curves
σ = f (ε). Develop a theory of the influence of structural factors (grain size, dislocation density,
dispersion hardening, hardening by substitution elements), temperature and strain rate on
physical plasticity δ *. Find the correlation of physical plasticity δ * with elongation to failure δ
at standard mechanical tensile test for various groups of metal alloys. Develop the method of determining the mechanical properties (yield strength and ductility) of the surface layers of materials and coatings by hardness.
