Abstract Scope |
Metal matrix composites composed of copper-tantalum were consolidated at room temperature from powder blends with the use of equal channel angular extrusion (ECAE). A total of five different processing routes were applied, with 1, 2 or 4 extrusions for each sample. The extrusion routes were selected in order to produce metal composites with elongated or equiaxed morphologies of the constituent phases. Samples were subsequently heat treated at copper homologous temperatures between 0.2 and 0.9. Mechanical behavior was characterized through hardness measurements and small-scale tension and compression tests under quasi-static conditions. This work was done to investigate the effectiveness of ECAE for powder consolidation as well as create model materials for investigating the impact of phase and grain boundaries on the mechanical behavior of FCC-BCC composites. |
