dc.description.abstractLaser Metal Deposition (LMD) is an additive manufacturing technique for manufacturing complex near net shaped components. The grain size of the typical deposition microstructure in case of Ti-6Al-4V can range between 100µm-600µm, which is much larger than that of forged-like microstructures. Friction Stir Processing (FSP) has been investigated as a method for surface modification to form refined microstructure at the surface of the Ti-6Al-4V components manufactured from the LMD method. Integration of FSP and LMD can greatly improve the product properties. Friction stir processing of the laser deposited Ti-6Al-4V deposits was performed and optimum processing parameters were obtained using this hybrid process. The microstructure of the nugget regions obtained in the substrate weld, stir over deposit and deposit over stir experiments is presented. A much decreasing grain size was observed in the dilution zone inside the nugget from the stir surface to the bottom of the dilution zone.en_US
