摘要

摘要: 采用滑移平面作为临界平面,并以滑移平面上的细观参量作为损伤参量研究材料损伤行为能很好地体现镍基单晶破坏的物理机制.滑移平面上细观参量通过本构模型相互联系,存在较强的多重共线性,导致寿命建模时难以得到合理稳定的材料常数.为此,引入主成分分析方法消除初始细观参量间的多重共线性影响,确定了临界平面主导损伤因子,并基于主导损伤因子建立了寿命模型.对比直接采用初始细观参量建立的寿命模型,该模型形式更为简单,材料常数稳定、合理,反映了细观参量对镍基单晶损伤影响的量化特征.采用760℃与980℃下DD6高温疲劳试验结果对寿命模型进行验证,试验寿命基本落在预测寿命的3倍分散带内.

Abstract: Fatigue damage in single crystal nickel superalloys is closely related to crystallographic slip along definite crystallographic planes. Thus, it is physically motivated to consider these crystallographic planes as critical planes. The mesoscopic parameters on the critical plane are all connected to the viscoplastic constitutive model, leading to inevitable multicollinearity among them. To address this issue, principal component analysis was performed to eliminate the effect of multicollinearity and determine dominant damage factors. Furthermore, a life model was formulated based on the determined orthogonal dominant damage factors. Compared with the life model which is directly formulated by the original mesoscopic parameters, result shows that this model is much simpler with reliable and stable material constants. The life model is then validated with isothermal fatigue testing results of DD6 at 760℃ and 980℃. Most of the predicted lives are within the triple factor of the measured lives.
