The fatigue cracking modes and corresponding microstructural information (IMAGE)
Caption
(a) Schematic illustration for our precise sectioning technique on the location of fatigue crack initiation; maximum stress and cycles to failure for (b) NAMP state; (c) HIP state; (d) HIP+STA state. The fatigue cracks of the NAMP state initiate from the clean PBGBs, which is a common characteristic in the AM microstructure, indicating that we have detected the fatigue resistance of the Net-AM microstructure.
