Abstract
This study focuses on four types of TixZrVNb (x = 1, 2, 3, 4) high-entropy alloys. After solution treatment, the alloys are subjected to room-temperature tensile testing. Characterization methods such as optical microscopy, scanning electron microscopy, electron backscattering diffraction, and transmission electron microscopy are used to analyze the microstructure of solution treatment. The results indicate that the microstructures of all four alloys are composed of grains with a single BCC structure. The room-temperature tensile test results indicate that as x increases, the yield strength of the alloy gradually decreases, while the plasticity gradually increases. On the basis of this experiment and to find an acceptable strengthening model, three solid solution strengthening models are introduced in this article, which are used to calculate the yield strength of solid solution alloys. The tensile yield strength of alloys is compared with the calculated values, and the differences between the three models and the error between the calculated results and experimental results are discussed. The results show that all three models can predict the yield strength of alloys well with an error of less than 8%; compared to other models, these models have smaller computational errors, among which the Varvenne model has a relatively small error.
