| Abstract: | Plastic deformation and rate-controlling mechanism during tensile deformation of various body-centered cubic (BCC) medium/high-entropy alloys (MEAs/HEAs) were investigated at 300 K. Microstructural ob- servations revealed long, straight screw dislocations, occasionally consisting of jogs. The deformed sub- structures were consistent with the evaluated activation volume ( V ∗) indicating screw dislocation mo- tion overcoming the Peierls-Nabarro stress barrier as the rate-controlling mechanism |
