| Abstract Scope |
A high – throughput method to quantify recrystallization parameters would be helpful to manufacturers trying to design heat treatments for high – entropy alloys, where the compositional space is large.
We describe a method to create partially recrystallized microstructures as a function of tensile strain in a single deformed and annealed sample. The inhomogeneous microstructures contain three zones: a fully recrystallized zone, a partially recrystallized zone and an unrecrystallized zone. The conditions for strain at onset of recrystallization and strain for full recrystallization and recrystallized grain size for given annealing conditions are readily identified. Results are validated against uniformly deformed samples after equivalent heat treatments.
This method enables optimisation of heat treatments for novel materials, and for materials where little data on thermomechanical processing has been published. Other high – throughput tests of grain size-dependent properties could be performed using these gradient microstructures. |
