Microstructural evolution and mechanical behavior of metastable β-type Ti–30Nb–1Mo–4Sn alloy with low modulus and high strength
A metastable P-type Ti-30Nb-lMo-4Sn alloy with ultralow elastic modulus and high strength was fabricated.Under the solution treatment state,the Ti-30Nb-1Mo-4Sn alloy possesses low yield strength of about 130 MPa owing to the presence of the coarse α " martensitic laths.Upon a cold rolling a...

| description | A metastable P-type Ti-30Nb-lMo-4Sn alloy with ultralow elastic modulus and high strength was fabricated.Under the solution treatment state,the Ti-30Nb-1Mo-4Sn alloy possesses low yield strength of about 130 MPa owing to the presence of the coarse α " martensitic laths.Upon a cold rolling and annealing process,the martensitic transformation from β to α" is significantly retarded due to the inhibitory effect of grain boundaries and dislocations.As a result,the metastable β phase with low total amount of β-stabilizers is retained to room temperature,giving rise to a low modulus of 45 GPa.Meanwhile,nano-sized a precipitates and dislocation tangles play a key role in strengthening the Ti-30Nb-1Mo-4Sn alloy,resulting in a high tensile strength of ~ 1000 MPa.With low elastic modulus and high strength,the metastable P-type Ti-30Nb-1Mo-4Sn alloy could be a potential candidate for biomedical materials. |
