| Popis: | In the present work, interfacial properties of a two-layered Aluminium-Copper (Al-Cu) functionally graded materials (FGMs) were fabricated by powder metallurgy method. The volume fraction of Cu (5, 10 and 15%wt.) powder mixture was hot pressed with a pressure of 400 MPa and sintered at 550 °C for 3 h as layer by layer. A complete characterization of the FGMs were analyzed by using optical microscope (OM), back scattered electron mode (BSE), scanning electron microscopy (SEM) and XRD of the interface microstructure. It is observed from the results that the mechanical and microstructural properties of FGMs varies gradually by increasing the material composition. The properties of FGMs was carried out in order to compare with homogeneous mixture of Non-FGM samples. It is observed from the results that the 10%wt. Cu FGM achieved good interface microstructure, micro-harness and relative density as compared to 5 and 15 wt Cu FGMs. |
