Ultra-high cycle fatigue property of a multiphase steel microalloyed with niobium

Effects of Niobium Addition on the Mechanical Properties and Corrosion Resistance of Microalloyed Steels: A Review

“…Although several investigations show the benefits of Nb addition in steels subjected to quasi-static loading, a few studies have explored the behavior under cyclic loading. Zhao et al [43] analyzed the behavior of Nb-microalloyed steels subjected to ultra-high fatigue cycles (109 cycles). A parameter evaluated in the study was the ratio of fatigue limit to the tensile strength measured under quasi-static conditions.…”

Ultra-high cycle fatigue behavior of a novel 1.9 GPa grade super-high-strength maraging stainless steel

“…3 components in industries are demanded to have higher service life. The fatigue lives of bridges, vehicles, railways and aircrafts are expected to be higher than 10 8 cycles [16] . For most of the components and structures such as landing gears, the main reason for fatal failure was sudden and severe fatigue damage.…”

Effect of fisheye failure on material performance inducing error circle under high cycles

“…Masuda et al (1985Masuda et al ( , 1986 carried out the ultra-high cycle fatigue test of carburized Cr steel, the experimental results found that the fatigue failure still occurs after the number of cycles beyond 10 7 cycles, the S-N curve presents obvious "ladder shape". Zhu et al (2020) and Zhao et al (2018) observed that when the fatigue life N f < 10 7 cycles, surface fatigue failure mainly occurs. When the fatigue life N f > 10 7 cycles, the internal inclusion is the main reason of internal failure of crack source.…”
