There has been considerable technological interest in high-entropy alloys (HEAs) since the initial publications on the topic appeared in 2004. However. only several of the alloys investigated are truly single-phase solid solution compositions. These include the FCC alloys CoCrFeNi and CoCrFeMnNi based on 3d transition metals elements and BCC alloys NbMoTaW. https://www.popularfilm.blog/
