Original methods of strength evaluation based on the indentation data were developed. Scientific fundamentals of limit strengthening of metals by the ultrafine grain structure formation using different technologies of materials production were founded. Regularities of plasticity, fracture and structure sensitivity micromechanisms of mechanical properties at micro- to nanostructure transition have been established.
