Refractory high-entropy alloys (RHEAs) have remarkable properties like high strength and thermal stability at temperatures. Their practical application is hindered by ambient brittleness inferior formability. Titanium (Ti) recognized as a crucial element in improving the ductility oxidation resistance of RHEAs, but its plasticizing mechanism still unclear. To address this, series body-centered cubic (BCC) single-phase VNbTaTix were designed. The exhibited exceptional cold-rolling formability room temperature. Remarkably, tensile fracture elongation VNbTaTi alloy was about 26.9%, which surpassed most RHEAs. major plastic mechanisms are a/2<1 1 1>-type dislocation {1 2}<1 twinning. Solid solution strengthening identified primary mechanism. Although Ti reduced solid effect, it contributed to weight reduction enhanced local lattice distortion. This study not only designed several RHEAs with also provided insights into effect content on their phase stability, distortion, mechanisms. These findings significant implications for designing new ductility.
