| Abstract Scope |
This presentation will discuss the observed phase transformations and microstructural evolution that accompany rapid solidification of austenitic stainless steels by splat quenching. Splat quenching is a method that is comparable in cooling rates to fusion-based additive manufacturing but with greater control over the solidification process. This talk will describe the changes in solidification behavior for five different chemistries of 316L stainless steel with intentional variation of Cr/Ni equivalences. The starting alloys were produced via arc melting. Splat quenching is used to reach cooling rates in the range of 105-106 C/s. Electron microprobe analysis (EPMA) and electron backscatter diffraction (EBSD) will be used to determine changes in primary solidification phase and to key solidification parameters at these extremely high cooling rates. This work was funded by the Department of Energy’s Kansas City National Security Campus which is operated and managed by Honeywell Federal Manufacturing Technologies, LLC under contract number DE-NA0002839. |
