Effects of temperature on the laws of plastic deformation and mechanical characteristics foils al coated with titanium nitride

The experimental results define the role of the coating of titanium nitride on a two-dimensional pattern of plastic deformation of polycrystalline aluminum at room and elevated temperatures. It is shown that the hardening of the titanium nitride coating 3 μm thick unable increase the strength of aluminum specimens, but can block the emergence and development rotational modes of plastic deformation and relaxation processes at elevated temperatures, leading to the occurrence of oscillation of the deformation stress on the deformation curves It is experimentally shown that the nature of the destruction of the coating, which leads to the destruction of the sample depends on the deformation temperature
