摘要

摘要:
针对镍基高温合金在热腐蚀环境下由蠕变-疲劳引起的失效问题，开展了一种基于连续损伤理论的腐蚀-蠕变-疲劳寿命预测方法。建立了DZ125镍基高温合金在腐蚀-蠕变-疲劳的复杂受力状态下的本构方程和损伤演化方程，开发用于计算的用户子程序。对不同温度下的DZ125合金的腐蚀-蠕变-疲劳寿命进行预测。通过模拟材料的全寿命损伤演化过程，以研究材料在不同温度及保载时间下的损伤机制。结果表明：寿命预测均在3倍分散系数范围内。损伤演化曲线显示，在850 ℃下，DZ125合金主要以腐蚀损伤为主，而在980 ℃下，蠕变损伤则主导了损伤演化过程。研究成果对于航空发动机热端部件的强度设计与寿命评估具有重要的意义。

Abstract:
Considering the failure of nickel-based superalloys due to creep-fatigue in hot corrosive environments, a corrosion-creep-fatigue life prediction method based on the continuous damage eigenstructure was proposed. The ontological equation and damage evolution equation of DZ125 nickel-based superalloy under the complex stress state of corrosion-creep-fatigue were established, and the user subroutine for the calculation was developed. The corrosion-creep-fatigue life of DZ125 alloy at different temperatures was predicted. The full-life damage evolution of the material was simulated to study the damage mechanism of the material at different temperatures and holding times. The results indicated that the life predictions fell within three times the dispersion factor. The damage evolution curves showed that at 850 ℃, corrosion damage dominated the damage evolution process in DZ125 alloy, while creep damage dominated the damage evolution process at 980 ℃. The research results are of great significance for the strength design and life assessment of aero-engine hot end components.
