Fabrication of Aluminium Metal Matrix Composite by Friction Stir Processing

Friction Stir Processing (FSP) is a new approach for successful fabrication of Aluminium Metal Matrix Composites (AMCs) with required properties of Nitinol (NiTi) Shape Memory Alloys (SMA). This reinforcement agent is used for heightening the mechanical properties of aluminium alloy with Shape Memory Effect but such fabrication was not possible without defects such as critical intermetallic formation between reinforced particles and matrix. So we present a creative strategy to fabricate Al7075-T6/NiTi composites by FSP. It has been found that the groove filling method results in a more homogenous distribution compared to the multi-holes filling method. In this innovative strategy, we are going to use the groove filling method with a new FSP tool design for the linear distribution of reinforcement particles in grooves. This FSP tool will be used with the help of a Vertical Milling Machine.
