摘要

•Laser welding between a CoCrFeMnNi high entropy alloy and 316 stainless steel was performed.•Joint ductility increased from 5 to 10 % by changing the CoCrFeMnNi high entropy alloy from rolled to annealed condition.•The joints strength is preserved at ≈ 450 MPa regardless of the CoCrFeMnNi high entropy alloy condition.•The CoCrFeMnNi / 316 stainless steel joints can be considered for structural applications.
