蠕变裂纹扩展的研究,首要的是确定表征蠕变裂纹扩展性能的合理判据,本文报导了对燃气涡轮盘常用材料GH33A合金蠕变裂纹扩展4种判据的研究结朱,求得最佳关联该合金蠕变裂纹扩展的参量,为进一步估算寿命打下基础
The primary research of creep crack propagation is to determine the reasonable criterion for characterizing the creep crack growth performance. This paper reports the research results of four criteria for creep crack growth of GH33A alloy, a commonly used material for gas turbine disks, Associated with the creep crack growth parameters of the alloy, to lay the foundation for further estimation of life expectancy
