Mechanical Properties of AA2024 In the Presence of Al-Cu IntermetallicSurface Layer

In this research, in-situ intermetallic surface layer based on Al-Cu alloying system were produced on Al2024 plate by friction stir processing (FSP). Then, microstructural and hardness properties of these specimens were investigated. To removal defects of conventional methods to produced surface layer by FSP, in this study, a new procedure was introduced for applying the reinforcement. So that at firstly, a new composite layer based on Al and Cu was produced by accumulative roll bonding (ARB). ARB composite layer were placed and fixed on Al2024 plate. ThenFSP were performed by rotation and travel speed of 1000rpm and 63 mm/min. Microstructural evaluation was performed by Scanning Electron Microscopy (SEM). In order to examine the effect of FSP process on hardness behavior, hardness test were performed on base metal and intermetallic surface layer
