Abstract: The mechanical properties and electrical conductivity of the in situ deformed Cu-14.5%Fe composites were investigated. The results showed that the Young's modulus of the composites is 134.41 GPa, which is approximately in agreement with the predicted value 138 GPa by ROM (rule of mixture). The investigation on the strength of Cu-Fe composites indicated that the ROM is not suitable to the prediction of the strength of Cu-Fe composites when the drawing ratio is greater than 5. The relationship between the strength as the excess over the value predicted by ROM, ΔσD, and the interfiber spacing d should satisfy the formula ΔσD=-188+465×d-1/2. The resistivity of the composites is affected mainly by the Fe content, while the conductivity fluctuates between 49.54%IACS and 56.89 %IACS.
