Abstract Scope |
Solid state deposition leads to layer by layer deposition of material, without any melting and solidification during the process. In the present work, friction stir metal deposition is employed to fabricate a three dimensional wall structure of Inconel 600. The deposition of Inconel 600 is performed at 1500 RPM, with a plunge feed of 0.8 mm/s and a forward feed rate of 8 mm/s. An average layer thickness of 0.6 mm is obtained. The microstructure at the interface of the consecutive layers revealed the dynamic recrystallization driven grain refinement. The electron backscattered diffraction results show that most of the grains are equiaxed. The grains near the interface ae as small as 0.4 μm. Further, the reduction of twin boundary fraction by ~30% is observed, in comparison to the initial microstructure of the stock. The texture analysis showed the presence of gauss and rotated cubic texture in the Inconel 600 deposits. |
