Effects of LPBF printing parameters on the columnar-to-equiaxed grain transition in FeCoCrNiMn alloys

Effects of LPBF printing parameters on the columnar-to-equiaxed grain transition in FeCoCrNiMn alloys

Abstract In this research, laser powder bed fusion (LPBF) technology was utilized to fabricate FeCoCrNiMn high-entropy alloys (HEAs). An integrated approach combining simulation and experimental research was employed to investigate the influence of process parameters on the columnar-to-equiaxed tran...
