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...

description 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 with compositions corresponding to Cu-10vol.%NbC-10vol.%TiC, Cu-15vol.%NbC-15vol.%TiC and Cu-20vol.%NbC- 20vol.%TiC were mechanical alloyed using a planetary ball mill for 5, 10, 20 and 30 hours. The as-milled powders then were cold pressed at compaction pressure in range of 500-1000 MPa and sintered in a vacuum sintering furnace for 1 hour at different temperatures from 700 to 1000oC
