Abstract Scope |
Although Inconel alloys are useful to build structural parts for turbine system, its maintenance is not convenient. So the replacing parts becomes popular strategy though it requires high cost and time. To overcome this problem, repairing technology through directed energy deposition (DED) is one of the attracting issues and many studies are being conducted. However, DED easily causes external defects such as voids and cracks, which result in the deterioration of the mechanical properties of the products. Hence, reducing external defects is essential, but the optimization strategy has not yet been clearly established due to the various processing parameters of DED. Therefore, the present study applies the response surface methodology (RSM) to control the defects and properties of Inconel 625 samples fabricated by DED. Based on the derived optimal conditions via RSM, we can obtain the optimal samples for evaluating their mechanical properties in various conditions. |
