Additively Manufactured High-Entropy Alloys:Exceptional Mechanical Properties and Advanced Fabrication

扫码查看
High-entropy alloys(HEA)represent a novel material class,with significant potential for research on performance and preparation in additive manufacturing(AM).Currently,FCC HEA dominates the research on AM-fabricated HEA,with a shift in focus from preparation to microstructure design and mechanical properties enhancement.Research on BCC HEA is currently primarily focused on preparation and process optimization.However,it is important to note that the biomedical potential of AM-fabricated BCC HEA should not be overlooked.This review provides a concise summary of the properties and preparation techniques of exceptional HEAs in recent years.It specifically emphasizes the novel microstructure achieved through AM techniques,which significantly enhance the mechanical properties of HEAs.Additionally,the review outlines the various preparation methods employed to mitigate defect introduction during AM processes.Finally,it offers insights into the future research directions and potential applications of additively manufactured HEA.
