摘要：

The low cycle fatigue behavior and mechanisms of fatigue damage initiation and propagation of several SCS-6 fiber-reinforced titanium alloy composites at room temperature were investigated. The fatigue damage diagram was constructed using the maximum stress in the fiber vs. fatigue life. Depending on the stress levels applied, the fatigue damage of the composites can be classified into three regions: (1) fiber breakage dominated, (2) interfacial cracking, matrix cracking and fiber breakage dominated (progressive) and (3) matrix cracking dominated. The microstructural parameters which affect the low cycle fatigue behavior of these composites are also discussed.
