| Abstract Scope |
IN625 possesses high strength and oxidation resistance, due to which it is preferred in aerospace and nuclear applications. Additive friction stir deposition of IN625 was carried out on SS316 substrate. Conventionally produced IN625 bar stock was used a feed material for deposition at 600rpm rotational velocity, 1.27mm/s liner tool velocity, and 0.27mm/s feed rate. The layer thickness of 0.5mm and deposit length of 50mm to deposit 4 layers. The deposited material was then examined by optical microscope, X-ray diffraction, scanning electron microscopy, electron back scattered diffraction and nanoindentation tests. The SEM and EBSD observations showed significant grain refinement of the deposit compared feedstock. Moreover, the interface showed significant extent of in-grain misorientation. The nanoindentation tests showed slight improvement in the hardness of 4.81GPa and reduced modulus of 218.65GPa, while the substrate measured hardness of 3.72GPa and modulus of 204.18GPa. |
