Effect of Yield Strengths on Fracture Behavior for 32CrNiMoV Steel
摘要
研究了屈服强度 σ0 .2 对 3 2 Cr Ni Mo V钢断裂行为的影响 .结果表明屈服强度 σ0 .2 对疲劳裂纹扩展门槛应力强度 Δ Kth,断裂韧性
The effect of yield strengths on fracture behavior for 32CrNiMoV steel has been investigated. The result shows that the effect of yield strengths on fatigue crack growth threshold value Δ K th , fracture toughness K IC and impact toughness α K is very big.
