Abstract Scope |
One of the ways to enhance the sink strength or radiation resistance in alloys is to introduce multiple interfaces via secondary phase precipitation. High Entropy Alloys offer significant potential for inducing such microstructural heterogeneities, but the conventional processing route involving casting is tedious and time-consuming. Advanced Manufacturing Methods such as Solid Phase Processing (SPP) offer an effective alternative to the traditional route for producing heterogeneous microstructures. In this work, a precipitation-strengthened HEA, Al0.3Ti0.2Co0.7CrFeNi1.7, is fabricated via shear assisted extrusion process, followed by a straightforward one-step annealing heat treatment exploiting the residual stresses is presented to engineer the heterogeneous microstructures successfully. The evolution of the heterogeneous microstructures in the as processed state and subsequently annealed condition and their nano indentation behavior, essential for nuclear applications (from Room Temperature to 800°C), will be discussed and compared with additively manufactured and subsequently annealed counterparts in the presentation. |
