Combining high strength and good ductility is a long-standing and challenging goal for metallic materials in modern engineering applications. Recently developed single-phase high and medium-entropy alloys, particularly those featuring heterogeneous microstructures, demonstrate superior strength-ductility synergy. Here, a single-phase CrCoNi-based m...

The dynamic tensile behavior of a novel-developed plate steel with high strength and toughness is investigated. Uniaxial tensile tests are conducted at various strain rates varying from 0.1 s−1 to 1000 s−1, and then scanning electron microscope and electron backscattered diffraction analyses are performed on tensile specimens at failure. A large an...

Complex-concentrated alloys (CCAs) have received a lot of attention recently due to their exceptional balance between strength and ductility. In this work, a brittle intermetallic compound strengthening Ni46.3Fe21Cr18.5Al10V4.2 (at. %) CCA has fabricated via carefully two-step thermomechanical treatment. The microstructure, phase composition, and m...

Complex-concentrated alloys (CCAs) have gained significant attention in recent years due to their exceptional combination of high strength and ductility. In this work, a novel Cr 18.5 Fe 21 Ni 46.3 V 4.2 Al 10 (at. %) CCA was designed and prepared. The dual-precipitates microstructures with hard B2 precipitates and coherent L1 2 nanoprecipitates, w...
