Abstract Scope |
The ability of some additive manufacturing techniques such as laser powder bed fusion (LB-PBF) for alloying in situ allows for the fabrication of compositionally graded alloy (CGA) coupons which can be utilized for fast screening of potential new alloys and/or fabrication of functionally graded engineering components. Towards these ends, we have explored several different CGAs that are fabricated using LB-PBF with variations in the powder supply mechanisms, gradient direction (with respect to the build direction), and the degree of powder mixing. Resulting microstructural evolutions and the chemically heterogenous mesostructures, and the effects of them on the mechanical properties of the fabricated parts are investigated. I shall discuss these results and surprising findings in this talk. |
