Abstract Scope |
The microstructures of metal parts produced via additive manufacturing (AM) are often very different than those produced by other methods such as casting or forging. As-built AM parts are often strongly textured which causes them to have anisotropic mechanical properties. While for many applications this may be undesirable, there are certain cases, such as when creep must be limited, in which this could be advantageous. In this work, the superalloy Haynes 282 was printed via laser powder bed fusion (LPBF). The effect of process parameter selection on microstructure was studied, with a focus on developing highly textured microstructures that could be beneficial for directional creep properties. Experimental heat treatments were also performed to determine a heat treatment cycle that could preserve the original texture of the AM parts while also allowing the desired precipitate structure to form. |
