After achieving the desirable properties in the AlCoCrFeNi2.1EHEAs, it naturally follows to analyze the strengthening mechanisms lying behind the enhanced strength–ductility synergy. Here, only upon a clear comprehension of the deformation processes of the hierarchical DPHL HEAs can we reasonably accou...
The strength-ductility synergy in TZK alloy was achieved by a combination of aging, extrusion and novel DT-ECAP process.The appearance of jogs or kinks highly contributed to the continued plastic straining during DT-ECAP process.The high strength originated from the strengthening mechanisms of grain...
Realizing improved strength–ductility synergy in eutectic alloys acting as in situ composite materials remains a challenge in conventional eutectic systems, which is why eutectic high-entropy alloys (EHEAs), a newly-emerging multi-principal-element eutectic category, may offer wider in situ composite ...
