Experimental Investigation of Tensile Properties and Fracture Mechanism of WC_P/Cu Composites Reinforced with Different WC_P Volume Fraction

Abstract:

The copper matrix composites reinforced by different WC_P volume fraction were fabricated via Vacuum Hot-pressed Sintering technique. The tensile performance and fracture behavior of WC_P/Cu composites were studied by uniaxial tension tests and the fracture surfaces were examined by SEM. The test results of mechanical properties show that the WC_P/Cu composites exhibit obvious improvement of tensile property comparing with that of the matrix. The fracture surface morphology indicate a trend that the fracture of WC_P/Cu composites changes from debonding to cleavage with the increase of the WC_P volume fraction.
