Friction stir spot welding (FSSW) is a relatively new process that may have significant advantages compared to the fusion processes as follows joining of conventionally non-fusion weldable alloys, reduced distortion and improved mechanical properties alloys joints due pure solidstate metals. In this paper, three-dimensional model based on finite element analysis used study thermal history in sp...

Abstract The focus of this study is to see if Friction Stir Processing can improve the properties an aluminium alloy with Boron Nitride (BN) particles on surface. (FSP) a new surface alteration technique that uses friction cause plastic deformation, resulting in grain refining and improved mechanical properties. To process 2024 plates, straight cylinder tool was used under varying parameters co...

In this study, Aluminium2024- Graphite composites containing 5, 10, 15 and 20 weight percent of graphite were produced by solid assisted melt disintegration (SAMD) technique which resulted in production of Al/Gr powder mixtures which subsequently consolidated and sintered for preparation of Al/Gr composites. In this technique, powder mixture was prepared by addition of flake graphite (mean diam...
