title = "Study on tensile fractured surfaces and toughening mechanism of Ti/Ti-Al micro-laminate sheet",
abstract = "Large-sized Ti/Ti-Al micro laminated thin sheet with thickness of 0.12mm was prepared byhigh-power electron beam physical vapor deposition technology, and then tensile tests of specimenafter hot-pressing densification were carried out at room and high temperature, and tensile specimenwas examined the fractured surfaces by SEM and OM. It was found that the tensile specimen underroom temperature presents a compound quasi-cleavage and intergranular fracture, and a certainplastic deformation of Ti toughening layer was detected during fracture process. Tensile fracturedsurfaces under high temperature present the feature of compound dimple models and quasi-cleavage,furthermore, the size and the quantity of dimple exhibited an enhancing trend with test temperatureincreased. Results show that the cracks will stagger along the inter-laminar interface or the layer dueto which micro-laminate expresses a good characteristic of delayed fracture. The tougheningmechanisms are that the crack deflection and micro-bridge connection caused by the tougheninglayers increases crack propagation resistance.",
