| Abstract Scope |
Placing the right material at the right place provides a unique opportunity to utilize the capabilities of different materials in a multi-material system. Materials with extreme capabilities are, however, often complex to form a unitary compatible system and are not easy to manufacture. Combined with the powder based directed energy deposition additive manufacturing strategy, this research explores the possibilities of achieving functionally graded superalloys towards refractory alloys. The design, development and preliminary material characteristics explore possible path functions for avoiding brittle intermetallic phases between nickel based IN718 and niobium based C103 alloys. Such functionally graded materials (FGMs) are sought to provide site-specific properties of super alloys at one end and refractory alloys on the other end crucial for energy, aviation, and space sectors. |
