Printability and microstructure of the CoCrFeMnNi high-entropy alloy fabricated by laser powder bed fusion

[Display omitted] •The CoCrFeMnNi high-entropy alloy exhibits excellent printability.•Rapid cooling leads to epitaxial growth of fine cells within the melt-pools.•Repeated metal deposition induces grain selection via competitive grain growth.•Scanning strategy and grain selection govern microstructu...
