Enhancing the mechanical properties of multi-principal element alloys via constructing dual-heterostructures through the immiscibility between elements
A strategy utilizing the immiscibility of Cu-Fe to construct FCC/FCC dual-phase structures was proposed in this work. The dual-phase structure and L12-nanoprecipitates achieve multi-scale synergistic strengthening, significantly improving the strength. Meanwhile, all coherent low-energy interfaces significantly reduce stress localization, and ensure a very small ductility sacrifice rate.
期刊介绍:
Materials Science and Engineering A provides an international medium for the publication of theoretical and experimental studies related to the load-bearing capacity of materials as influenced by their basic properties, processing history, microstructure and operating environment. Appropriate submissions to Materials Science and Engineering A should include scientific and/or engineering factors which affect the microstructure - strength relationships of materials and report the changes to mechanical behavior.
