| Abstract Scope |
High entropy alloys (HEA) have attracted attention for various material applications because of their unique phase stability and diffusion kinetics, which could be leveraged in a nuclear application. To manufacture these advanced HEAs on a large scale, additive manufacturing is considered a viable method, such as electric field assisted sintering, since the raw materials of the HEAs usually come in powder form. A comparison of arc-melted and EFAS manufactured material radiation resistance was done using Ti 3+ ion irradiation with material compositions of MoNbTi, MoNbTiV and Nb2TiVZr2, at high temperature over a series of radiation doses. These materials were characterized using SEM and TEM to observe microstructure changes after irradiation and radiation damage. This work presents progress towards understanding resistance to high temperature, heavy irradiation damage in a candidate refractory HEA materials for use in advanced reactors, as well in understanding how different advanced manufacturing techniques affect radiation resistance. |
