The Effect of Hybrid B4C and Si3N4 Nanoparticles on the Mechanical and Physical Properties of Copper Nanocomposites

This study investigated the effects of reinforcing pure copper with hybrid B4C and Si3N4 nanoparticles on mechanical physical properties nanocomposite matrix. The composite matrix was prepared using powder metallurgy (PM) method, allowing uniform nanoparticle dispersion within PM method a practical approach for achieving homogeneous good particles in while controlling porosity improving microstructure fabricated addition are both very hard dense materials. When added to material, they can fill voids reduce porosity. lead significant improvements material’s properties. found that adding enhanced microhardness nanocomposites. such composites containing 5% were 21.6% 18.4% higher than base alloy. findings suggest including ceramic is viable strategy enhancing characteristics its form. For example, resulted 23% increase Young’s modulus material reducing electrical conductivity by 4.6%. On other hand, Cu/5%B4C + 2.5%Si3N4 showed 32% improvement 71% value compared metal. makes it promising option various engineering applications, as high-performance contacts bearings.
