Abstract
In this work, an alternative aluminium matrix composite (AMCs) was designed from the recycled chips of the aluminium, Alumix 431 given by Brazilian aeronautic company, through combined method of powder metallurgy followed by Sintering + Forging. We aimed for the application for the connection pieces to transfer motion mainly used in automotive and aeronautical area as an alternative replacement for conventional alloys used in this area. First of all, A typical matrix was developed from recycled aluminium (AA 431) chips by high energy milling in a planetary ball mill with an inert argon atmosphere to prevent oxidation of the powders and this matrix was reinforced basically with TiC (5 wt % and 10 wt %) and molybdenum and copper (Mo 4 wt %, Cu 4 wt %) as a secondary reinforcements respectively. Mechanical and physical properties were evaluated through micro-hardness, static compression and 3 point bending (PB) tests and impact-drop weight tests were carried out. The microstructure analyses have been carried out by Scanning Electron Microscope (SEM).
