Evaluation of pulsating tension fatigue strength and influence of microstructure on small crack initiation and growth behaviors of Ni based castalloy 246

Evaluation of pulsating tension fatigue strength and influence of microstructure on small crack initiation and growth behaviors of Ni based castalloy 246

The purpose of this study is to investigate low cycle fatigue (LCF) and high cycle fatigue (HCF) strengths, crack initiation and growth behaviors of Ni based castalloy 246. LCF and HCF tests are conducted under load controlled conditions. As the result of the observation of etched specimen, the grai...
