Powder mixtures obtained byadding Cr and C at various ratios into the Cu powder were shaped by applying apressure of 300 MPa. The specimens were sintered at different temperatures inorder to determine the optimum sintering temperature. The success of thesintering process was evaluated by density measurements. The microstructure andmechanical properties of the produced composite specimens are characterized.Microstructural characterization was performed by X-ray diffraction (XRD),scanning electron microscopy (SEM) and energy dispersive spectrometry (EDS)analyses. The effects of Cr and C addition on mechanical properties atdifferent ratios were evaluated by hardness measurements and tensile tests.Density measurements have shown that the relative density values ​​that can beachieved with increased Cr and C ratios are increased. XRD analysis showed thatCr formed carbide and nitride compounds in the microstructure during sintering.The hardness values ​​obtained with these Cr and C ratios increased with theincrease of these compounds.
