摘要

The plastic deformation and fracture processes of Ti-3Zr-2Sn-3Mo-25Nb alloy for surgical implants were directly observed by in situ scanning electron microscopy (SEM). The effect of phase transformations on deformation-induced martensitic transformation accompanying the cyclic tensile fracture processes was investigated. The results reveal that the metastable alpha martensites (α ^″) promotes deformation-induced martensitic transformation to ductile fracture, whereas the omega (ω) and alpha (α) phases drastically prevent slip dislocation and deformation- induced martensitic transformation to brittle fracture.
