The authors appreciate all experimental support provided by LNNano (CNPEM/MCTI) and recognize Petrobras by financial support.Ni-based superalloy Mar-M247 was evaluated as a potential tool material for friction stir processing (FSP) of X70 steel. The superalloy consists of a γ-γ’ structure and minor precipitates, such as MC carbide. FSP tests evaluated the tool performance at different rotation and welding speeds and the effect of shielding gas was also analyzed. Prior to FSP tests, hot compression tests showed that the tool material microstructure was stable below 950 °C, which affected positively its mechanical strength. It was observed the FSP tool overheating at rotation speed of 400 rpm. In this condition the γ-γ’ structure was destabilized forming “γ’ free zones” at the tool shoulder. In these zones new γ-grains were formed by recrystallization. Oxygen diffusion occurred at γ-grain boundaries embrittling the γ’ free zones that were ripped out by abrasion during FSP tests. The tool wear damage was mitigated by controlling friction processing parameters, such as rotation and welding speeds, Z-force values and gas shielding. The FSP made in this work improved surface properties of X70 steel.DEMI - Departamento de Engenharia Mecânica e IndustrialUNIDEMI - Unidade de Investigação e Desenvolvimento em Engenharia Mecânica e IndustrialRUNCosta, Alex Matos da SilvaOliveira, J.
