Near-threshold fatigue crack growth and fatigue strength of ER70S-6 steel processed by wire arc additive manufacturing

Abstract In this work, fatigue crack growth (FCG) tests were conducted to determine the threshold stress intensity factor ( ΔK th ) of ER70S-6 steel processed by wire arc additive manufacturing (WAAM). Samples were orientated with the crack direction (CD) both parallel (//) and n...
