$Using X-ray diffraction method, the effect of cold (23°C) and warm (200, 400 ºC) high-pressure torsion (HPT, 6GPa, N=1,3,5 full revolutions) on the structural parameters and phase composition of single crystals of high-manganese austenitic steel Fe-28Mn-2.7Al-1.3С (wt. %) was investigated. Regardless of the deformation temperature and the number of revolutions under HPT, steel retains an austenitic structure with high lattice parameter of 3.638-3.653Å; the microhardness of the steel increases, and its magnitude and radial-distribution substantially depends on the HPT temperature.$

A method for predicting nonlinear behavior of unidirectional reinforced composite is developed. It is based on nonlinear strain of matrix material described modified relations flow theory to account for the technological defects. The developed approach allows to build stress-strain curves of unidirectional-reinforced composite at tensile along the fibers, at tensile and shear in the reinforcement plane and explore resistance reinforced unidirectional composite complex loading.
