| Abstract Scope |
High-throughput testing has been identified as a key method required to identify specific high entropy alloys for commercialisation from the enormous compositional search space. Here a method of parallel microstructural testing is demonstrated in alpha brass that shows potential for accelerating alloy testing and qualification.
We use finite element analysis to design samples with controlled, inhomogeneous cold work. Subsequent interrupted annealing and optical characterisation allow the determination of recrystallisation and grain growth behaviour. We validate (i) sample design against strain from digital image correlation and (ii) grain size analysis using optical methods against EBSD methods. The results derived from gradient samples compare favourably with those obtained from homogeneous samples. The potential of this method to be used in alloy testing and qualification will be discussed. |
