摘要: The damage process leading to fracture during tensile testing of a biomedical grade Co–29Cr–6Mo–0.14N alloy was analyzed on the basis three-dimensional observation using X-ray tomography and electron backscattered diffraction fractured specimen. Initial cracking occurred at grain annealing twin boundaries, where strain concentrates due impingement e-hcp plates formed through strain-induced martensitic transformation (SIMT). Cracks propagated along interface between γ-fcc matrix SIMTed {1 1 1}, resulting in occurrence quasi-cleavage fracture.
