概要
- 論文の詳細を見る
The fatigue crack growth tests were performed on low carbon structural steel with five different microstructures, i.e. steel with pearlite particle (15 and 50μm grain size), with bainite particle (15 and 5μm grain size) and with martensite particle. The results showed that microstructure influence fatigue crack growth behavior in both threshold region and Paris region and the presence of hard phase enhances fatigue crack growth resistance. The results were discussed based on the crack path observation and crack closure behavior
