Since the discovery of high-entropy alloys (HEAs) in 2004, considerable efforts have been made to understand phase formation mechanisms and microstructural development of these multicomponent alloy systems. HEAs were initially restricted to those alloys that have at least five principal elements with equiatomic concentration. Since then such restriction has been lessened by the introduction of multiprincipal element alloys (MPEAs) and complex concentrated alloys (CCAs). The alloys generally lead to the formation of multicomponent FCC, BCC and/or HCP solid solutions. It has also been observed that some of these alloys will go through liquid phase separations. In this presentation, after a brief review of the literature, results of our recent investigation of solidification and microstructural development of 3-d transition metal HEA systems will be introduced. In addition, results of in-situ neutron imaging of their liquid phases will also be presented.
