Abstract:

 This study aims to investigate the effect of mechanical alloying time on the microstructure, hardness, and electrical conductivity properties of copper Cu matrix boron carbide B4C reinforced composites. Cu-B4C composites with 2 B4C by volume were subjected to mechanical alloying processes for 0, 1, 5, 10, and 20 hours. The microstructure and phase formation of the composites were examined using scanning electron microscopy SEM and X-ray diffraction XRD. Hardness measurements of the composites were conducted using the microhardness measurement method, and density values were determined using the Archimedes principle. The electrical conductivity values of the samples were measured in terms of the international annealed copper standard IACS based on the eddy current principle. SEM images revealed a more homogeneous distribution of B4C particles in the Cu matrix as the mechanical alloying time increased. Hardness values showed significant increases with the increasing mechanical alloying time, reaching the highest value in the 20 h milled sample with a 90.86 value. The effect on electrical conductivity values was noteworthy, with a measurement of 63 IACS at 0 hours and 25 IACS at 20 hours of mechanical alloying.
