Cold-rolling effects on the microstructure properties of 316L stainless steel parts produced by Laser Powder Bed Fusion (LPBF)

Laser Powder Bed Fusion (LPBF) technology provides new opportunities to enhance some piece-producing processes in the industry. Moreover, LPBF microstructures can heavily differ from microstructures usually obtained through traditional processes, especially 316L LPBF ones which combine both strength...
