Ti-Nb-Ta-Zr Alloy Rolling Deformation Texture

Article Preview

Abstract:

TiNbTaZr alloy is potential medical biomaterials, due to its high strength, low elastic modulus, superelasticity, superplasticity, and many other excellent performances. TiNbTaZr rolling samples under solid solution state and deformation state were characterized by TEM and XRD technologies. The results show that the alloy has the grain size of 42mm, straight of grain boundaries, intragranular no significant defects after solution heat treatment at 1063K. When the deformation reaches 40% in the rolling process, the local zones in intragranular appears high density of dislocations and a small amount of twinning. When the rolling is to 92%, the high density of dislocation cells forms nano subgrain block in sample with {100} plate texture and the texture axis of {100} plate under density of 2.29.
