Title : Micro-crack Initiation Mechanism of DZ125 Ni-based Alloy During Very High Cycle Fatigue
XU Luopeng, , ZHOU Min, , WANG Qingyuan,

Abstract : The DZ125 alloy has excellent mechanical, fatigue, and high-temperature behaviors. It has been widely used in high-temperature gas turbine components. Although a lot of researches have been carried out on the fatigue problem of the DZ125 alloy, there are still few systematical studies on the fatigue crack initiation mechanism and its failure mechanism during very high cycle fatigue (VHCF) by microscopic fracture analysis. It is found that the scatter of fatigue data increases as fatigue stress d
