摘要

通过描述微结构来表征典型轻型飞机钛合金的寿命行为,期望改进寿命计算。因此,对Ti-6-4拟合元件进行了广泛的研究。除静态拉伸试验、旋转弯曲试验和断裂力学试验外,还进行了恒载和变载构件试验。同时,试样和被测部件的微观结构在几个点进行了广泛的分析,包括凸耳区域,以及试样的微观结构,从较低的连接拟合中取出。在寿命计算中,通常考虑寿命结果以及微观结构的结果,这表明了更精确的寿命估计的可能性。

Material and component investigations on a Ti-6-4 fitting element
An improvement in the life time calculation is aspired by the characterisation of the life time behaviour of a typically lightweight aircraft titanium alloy by describing the microstructure. Therefore, extensive research on a Ti-6-4 fitting element has been carried out. In addition to static tensile tests, rotating bending tests and fracture mechanical tests, component tests with constant and variable load were performed. Simultaneously, the microstructures of the specimens and tested components are extensively analysed at several points including the lug area, as well as, the specimen’s microstructure taken out of the lower link fitting. A common consideration of life time results as well as results of the microstructure in the life time calculation shows the possibilities for more precise life time estimation.
