Superelasticity Evaluation of the Biocompatible Ti-17Nb-6Ta Alloy

ANISOTROPIC SUPERELASTICITY OF TEXTURED Ti-Ni SHEET

A recently developed crystal-mechanics-based constitutive model for polycrystalline shape-memory alloys (Thamburaja and Anand [1]) is shown to quantitatively predict the in-plane anisotropy of superelastic sheet Ti-Ni to reasonable accord. Keywords— Phase transformations, Constitutive equations, Finite-elements, Mechanical testing.

Microstructural Evaluation of Ti-6AL-4V Alloy during Hot Deformation

Among the titanium alloys, Ti-6Al-4V is the most widely used. In the present work, the uniaxial hot compressive behavior of Ti-6Al-4V has been investigated under constant strain rates. A series of dilatometery experiments were carried out to determine the transformation temperatures at different cooling rates. Specimens were homogenized at 1050 °C for 10 minutes followed by fast cooling to dif...

Comparison of the Microstructure, Tensile, and Creep Behavior for Ti-24Al-17Nb-0.66Mo (Atomic Percent) and Ti-24Al-17Nb-2.3Mo (Atomic Percent) Alloys

The effect of small molybdenum additions, 0.66 and 2.3 at. pct, on the microstructure, tensile, and creep behavior of a nominally Ti-24Al-17Nb (at. pct) alloy was investigated. The alloy containing 2.3 at. pct Mo contained higher body-centered-cubic (bcc) phase volume fractions, which was expected as Mo stabilizes the bcc phase. Constant load, tensile-creep experiments were performed in the str...
