Is established, that dispersivity of a refractory composition in microstructure, influences thim thermophysical property, that proves to be true of result of experimental researches specific thermal conductivity depending on dispersivity of a refractory composition in microstructure Cr-Cu. The microstructural changes of contacts Cr-Cu are investigated at switching a current in vacuum. Is established, that dispersive structure of a material of contacts promotes decrease of deterioration and propensity to thermal fatigue of a working layer.
