Refractory High Entropy Alloys (RHEAs) are a new and promising class of metallic alloys for structural applications at elevated temperatures. RHEA alloy development is challenging, due to the vast composition space characteristic of these multicomponent alloys. Predictive models are paramount for their development, so alloy design does not need to rely on trial-and-error experimentation. Unfortunately, the fundamentals that determine the solid-solution strengthening of RHEAs are not fully understood. In this work, compression stress-strain curves of seven RHEAs were generated at temperatures from room temperature to 1000 °C. The results are interpreted using a combination of models available for conventional body centered cubic (BCC) alloys. The temperature dependence of these alloys is interpreted to gain insight on the fundamentals of solid solution strengthening on the multicomponent field of BCC RHEAs.
