Effects of interface chemistry on the fracture properties of titanium matrix composites

摘要: Abstract The fiber–matrix interface plays a critical role in the performance of titanium matrix composites (TMCs). In this work, effect interfacial reactions on fracture properties is studied using experimental characterization and computational modeling techniques. objective study to establish link between evolution chemistry resulting mechanical properties. SCS-6/Timetal21s composite chosen as candidate material system. specimens are exposed temperatures high 927°C for extended periods. diffusion elements across investigated through metallurgical Fiber push-out used characterize interface. A novel method simulate propagation cracks during tests. toughness evaluated from data method.
