| Abstract Scope |
Welding or joining between two different materials is a critical issue in conventional manufacturing criteria.
The interface instability of two different components leads to catastrophic failures such as crack propagation and undesirable intermetallic formation.
Functionally graded material (FGM) method in AM is a suitable application for incidents that require multiple properties simultaneously, such as high corrosion resistivity via high-temperature durability.
The earlier solutions of FGM in the gradient interface were only given by the addition of alloying elements. Hence, controlling in-situ gas content alteration leads not only to detouring undesirable phases but also form beneficial inclusions toward the boundary. In-situ gas control method application in Inconel series and 316L stainless steel degraded creation of intermetallic phases and solidification crack. Microstructural assessment and mechanical property comparison determined; the reduction and oxidation behavior in the melt pool and inclusion (Nitride and oxide) formation mechanism in-situ atmosphere control will be majorly discussed. |
