Friction Stir Welding of Precipitation Hardened Ni Based Alloys
Commercial Waspaloy plates with two different initial microstructures (annealed and aged) were joined by Friction Stir Welding (FSW). This study presents the evolution of the grain structure, and precipitation, dissolution and reprecipitation of the γ' phase during FSW using Optical Microscopy,...

| Zusammenfassung: | Commercial Waspaloy plates with two different initial microstructures (annealed and
aged) were joined by Friction Stir Welding (FSW). This study presents the evolution of the grain
structure, and precipitation, dissolution and reprecipitation of the γ' phase during FSW using Optical
Microscopy, Scanning Electron Microscopy and Transmission Electron Microscopy. The
relationship between microstructure and microhardness is also discussed. |
