Purpose: This study aims to investigate the effect of mechanical peening on the cooling rate of a subsequently deposited layer in a hybrid additive manufacturing (AM) process. Design/methodology/approach: In this experimental study, 20 layers of 316 L stainless steel are built via directed energy de...
