Abstract Scope |
Despite recent progress developing more corrosion-resistant, radiation-resistant, and accident-tolerant materials, most next-generation reactors are still designed with materials from the 20th century due to the resource-intensive process of developing and qualifying new materials. The time and resource demand of alloy development increases with the number of alloys examined, further challenging the exploration of broad composition ranges, such as those occupied by compositionally complex alloys (CCAs). To accelerate both the synthesis, irradiation, and characterization of novel alloy compositions for nuclear applications, additive manufacturing has been employed to print bulk arrays of Cr-Fe-Mn-Ni compositions which can be processed and tested in a high-throughput manner. To perform high-temperature ion irradiations, a unique infrared laser heating system combined with an additively manufactured, water-cooled stage has been developed to uniformly cool entire compositional arrays while single coupons are heated. Discussion will include alloy synthesis, development of high-throughput capabilities, and ion irradiation results. |
