| Abstract Scope |
In this study, functionally graded material (FGM) of austenitic 316L Stainless Steel (STS) and iron based medium entropy alloy (MEA) in austenitic metastable phase were fabricated by direct energy deposition (DED). As a result of mechanical properties, the twin induced plasticity (TWIP) of STS and the transformation induced plasticity (TRIP) deformation behavior of MEA are shown to greatly delay the plastic instability and help in realizing materials with higher ductility. As a result, elongation was improved without compromising the strength. |
