概要
- 論文の詳細を見る
With particular attention to the effect of the specimen thickness, fatigue crack propagation behavior was experimentally examined on plate specimens of 3 hr aged and solution treated maraging steels and of carbon steel S55C. It is the major conclusion that the crack propagation rate tends to decrease with a decrease of the specimen thickness for each of the materials. Another finding in this study is that the crack opening ratio U tends to decrease in the crack growth process for the aged maraging steels, but the ratio increases to unity for the carbon steel.
