摘要：
The fracture behavior of notched TC21 alloy with lamellar microstructure has been investigated during the tensile deformation process. The crack initiates along the alpha/beta interface within the alpha colony at the notch. And the crack propagates along the slip band or near the colony boundary, which are far away from the notch. The fracture mode is a combination of ductile and quasi-cleavage fractures.
