Essay

The thesis research is devoted on the experimental investigation and theoretical study of physical processes in the range of elastic and plastic deformation of Cu/Cr and Fe/Cr two-layer film systems, which can be used as sensitive elements of high-temperature strain sensors. Peculiarities of the deformation dependences of the resistance, relative change of resistance, instantaneous and mean values of gauge factor on the deformation value and on the number of deformation cycle were revealed. Experimental check of phenomenological models for GF of two-layer film systems. Electron transfer parameters and their change under deformation for Cu/Cr and Fe/Cr films were calculated.
