Preparation Of In-Situ Carbides Reinforced Hybrid Copper-Based Composite By Mechanical Alloying And Its Characterization

The goal of this research work is to investigate the feasibility of the synthesis of two distinct in-situ carbides (NbC and TiC) simultaneously in a copper matrix via mechanical alloying and powder metallurgy from elemental powders of Cu, Nb, Ti and graphite. Three mixtures of starting powders wi...
