摘要:
金属间化合物基层状复合材料Ti/Al3Ti是采用Ti-6Al-4V箔和Al箔按照一定顺序叠加后,在真空环境下热压烧结成由韧性金属Ti和金属间化合物Al3Ti组成的叠层结构。利用ENF(End-Notch-Flexure)和MMF(Mixed-Mode-Flexure)测试方法,对Ti/Al3Ti层状复合材料的II型及I+II型层间断裂能、层间断裂行为以及能量释放率等方面进行了研究。结果表明,Ti/Al3Ti层间断裂时,裂纹在复合材料界面处发生起裂,而在传播过程中发生偏转,最终导致Al3Ti层开裂。由此可见,在实验过程中裂纹的表现形式是在Ti/Al3Ti界面及Al3Ti层中共同扩展;I+II型层间起裂能量释放率GI+II为46J/m2,II型层间起裂能量释放率GII为1453J/m2,表明II型层间断裂比I+II型层间断裂更困难。
Abstract:
Metal-Intermetallic Laminate (MIL) composite Ti/Al3Ti, which is a class of laminated material and consists of ductile Ti layers and intermetallic Al3Ti layers, is sintered using both Ti-6Al-4V foils and Al foils. In this paper, the methods of ENF (End-Notch-Flexure) test and MMF(Mixed-Mode-Flexure) test are used to investigate the interlaminar fracture energy of two fracture types (type II and type I + II), the interlaminar fracture behavior and the energy release rate of MIL composite Ti/Al3Ti. The results show that the crack initiation occurred at the interface between the layers, and the deflection occurred in the course of the crack propagation, which led to the crack of Al3Ti layer. Therefore, the cracks finally appeared to propagate at both the interface of composite and the Al3Ti layer. The interlaminar fracture energy release rates GI+II and GII are 46 J/m2 and 1453 J/m2, respectively, which show that type II interlaminar fracture crack requires more energy than that of type I + II.
