Abstract
Recently highentropy alloys HEAs have attracted much interest in the materials community as they offer massive opportunities to observe new phenomena explore new structure and develop new materials Particularly it is attractive to prepare highperformance HEA coatings by laserinduced rapid solidification which can be formed on the surface of components and parts in a variety of sizes and shapes with a lower cost in comparison with those bulk material fabrication methods From the technical point of view laserinduced rapid solidification could hamper the compositional segregation improve the solubility in solidsolution phases and lead to the strengthening effect by the grain refinement This article reviews the recent work on the typical microstructural features and the mechanical and chemical properties in laserinduced rapidly solidified HEAs and these data are compared with conventional Co and Nibased alloy coatings The article concludes with suggestions for future research and development in HEAs from considerations of their characteristic propertiesThe authors thank the financial support from the National Natural Science Foundation of China under Grant No 51271001 the Open Project of Jiangsu Key Laboratory of Advanced Metallic Materials under Grant No AMM201201 and the University Natural Science Research Project of Anhui Province of China under Grant No KJ2014A063 Some of the work described in this review article was supported by a grant from the Research Grants Council of the Hong Kong Special Administrative Region China Project No PolyU 533910E
