The interior defect-induced crack initiation mechanism and early growth behavior of Ti6Al4V alloy fabricated by laser powder bed fusion (LPBF) has been investigated in very high cycle fatigue (VHCF) regime. P-S-N curves under 10% and 90% failure probabilities are obtained in VHCF regime. The cracks...
