Thermal conductivity of a composite material based on iron and copper powders and fibers

The temperature and concentration dependences of the thermal and electrical conductivities of a series of multicomponent composite materials with an iron-phosphorus base incorporating copper powder and fibers are analyzed. The effect of the structure and composition of the composite material, the shape of the particles, and the concentrations of the components on the conductivity of the composite material is investigated. The possibility of using computing methods for determining the conductivity of these composites is assessed.
