| Abstract Scope |
The inherent fast cooling rates during additive manufacturing (AM) of metallic alloys result in uncertainty and anisotropy in the location specific (LS) material properties. Such unique material characteristics can be correlated to the LS microstructure compromising the spatial characteristics of various phases (e.g size, morphology, and crystallography) and defects ( e.g. size, morphology etc). To enable certification of AMed parts for flight critical application, uncertainty in the LS properties need to be understood and quantified which can be achieved via understanding of LS microstructure evolution which can ultimately lead to tailoring the microstructure to achieve desired part performance.
In this talk, a summary of microstructure-property correlations will be presented for commonly AMed Ti6Al4V, AlSi10Mg, 316L and novel titanium superalloys (e.g. beta Ti185) and aluminum superalloys (e.g Al-Zr). Various material properties will be presented including tensile and fatigue responses with correlations to as-built and tailored (i.e. designed) microstructures. |
