Low Cycle Fatigue Properties in Forged TiAl Alloy Ti-43Al-5V-4Nb with Triplex Microstructure

On the Effects of Hot Forging and Hot Rolling on the Microstructural Development and Mechanical Response of a Biocompatible Ti Alloy

Zr, Nb, and Ta as alloying elements for Ti alloys are important for attaining superior corrosion resistance and biocompatibility in the long term. However, note that the addition of excess Nb and Ta to Ti alloys leads to higher manufacturing cost. To develop low-cost manufacturing processes, the effects of hot-forging and continuous-hot-rolling conditions on the microstructure, mechanical prope...

A New Ti–15Zr–4Nb–4Ta alloy for medical applications

V ions exhibit cytotoxicity in a culture medium from concentrations of ^0.2 mg/L. Ti, Zr, Nb and Ta are biocompatible elements. A new Ti–15Zr–4Nb–4Ta alloy for medical implants is being developed. Its microstructure, mechanical properties, corrosion resistance and corrosion fatigue properties in a physiological saline solution, biocompatibility with cultured cells, new bone tissue response thro...

Microstructure and mechanical behaviour of the isothermally forged Ti-6Al-7Nb alloy

The mechanical properties of the Ti-6Al-7Nb alloy, used to manufacture high-strength prostheses, are highly dependent on its microstructure. This work presents the microstructural changes of this alloy under isothermal hot working. It is shown that microstructure is strongly affected by strain rate, temperature and strain. The possible precipitation of intermetallic phases is also evaluated. To...
