In the present study, friction spot welding or refill friction stir spot welding was performed to consolidate dissimilar AA5754 Al and AZ31 Mg alloys. The intermetallic compounds of Al12Mg17 and Al3Mg2 were primarily found in the weld, distributed at the interface between the base materials and in the Al top sheet. The distribution of the intermetallic compounds and the interfacial area between...

Recognition of the friction stir welding process is growing in the aeronautical and aero-space industries. To make the process more available to the structural fabrication industry (buildings and bridges), being able to model the process to determine the highest speed of advance possible that will not cause unwanted welding defects is desirable. A numerical solution to the transient two-dimensi...

In most of the industries like automobile, aircraft, shipbuilding, etc., surface composites play an important role as they enhancestrength, hardness, and microstructure. Friction Stir Processing is a solid-state alteration engineering techniqueemployed for development Metal Matrix Composite surfaces. It enables surface, control microstructure,enhancement wear improvement in mechanical propertie...
