| Abstract Scope |
High entropy alloys have been attracing significant attention owing to their thermophysical properties. The same follows for additive manufacturing owing to its unique capabilities for fabricating complex geometries in a relatively simple manner. The multiprincipal element characteristic of high entropy allows coupled with the highly non-equilibrium conditions experience during fusion-based high entropy alloys renders the need to use advanced in-situ characterization to unveil the solidification paths and its effect on the mechanical performance of the fabricated alloys.
In this presentation, we will highlight recent studies where synchrotron ligh sources were used for: i) in-situ laser additive manufacturing of high entropy alloys; ii) in-situ mechanical response of the obtained materials; and iii) transformation kinetics during heat treatments of the same materials.
We will finalize with a brief perspective of what other instrumentation/experiments are need to further unveil microstructure/processing/properties relationships involving high entropy alloys. |
