| Abstract Scope |
Direct energy deposition(DED) method is an emerging manufacturing
technique that has recently been highlighted due to its capabilities to coat
materials with complex geometry. Carbon steel is widely used due to low cost, and SS316L exhibits superior corrosion resistance in extreme environments. Therefore,
additive manufacturing of carbon steel parts using SS316 powder can be a
promising techniques for the industry application. To obtain robust and
stable properties in extreme environments, optimization of manufacturing process conditions of SS316 is necessarily required.
In this work, the effects of process parameters are investigated using DED
method with a 4 way nozzle. It was found that laser power has an effect on
grain growth structure. To test mechanical properties, 3 point bending test
and Potentio dynamic test are performed. These results can be utilized in the
future studies to accelerate the process design time of other 3D printed
materials and future applications using SS316. |
