- In situ solid-solid phase transition observations in Ti alloys, AP.R
Abstract
This project aims to reinforce the collaborative research activities that have previously been established between Prof. Rubens Caram (University of Campinas - UNICAMP, Brazil) and Prof. Rian Dippenaar (University of Wollongong - UOW, Australia). The main scientific goal of this proposal is to investigate solid-solid phase transformations in titanium alloys using in situ observations in...

- Non-classic precipitation of alpha phase in Ti-Nb-Fe and Ti-Nb-Fe-Sn alloys, AP.R
Abstract
Mechanical behavior of metastable beta-type titanium alloys can be manipulated by applying solution heat treatments of beta phase, followed by alpha phase precipitation. While beta phase is soft, alpha phase exhibits harder. Usually, it is assumed that the alpha phase nucleation in the beta phase matrix occurs heterogeneously and assisted by omega phase, which acts as nucleation substra...
- Alpha phase nucleation in metastable beta type titanium alloys in the Ti-Nb-Fe system, AP.R
Abstract
In well different industrial segments such as aerospace and medical, the use titanium and its alloys in the manufacturing of devices has increased consistently in recent years. The use of such metal in a so varied manner, either in jet engines or orthopedic implants, is due to its unique characteristics, specifically high mechanical strength, low density, high corrosion resistance and g...

- Osteosynthesis plates with stiffness gradient based on metastable beta titanium alloys: theoretical and experimental analyses, BP.DD
Abstract
Functional gradient materials exhibit high potential for application in the manufacturing of orthopedic devices for implantation as they can minimize collateral effects related to implants in the human body. Titanium alloys can be tailored to obtain materials with functional gradients as their mechanical properties can be controlled by addition of specific alloying elements or by imposi...
- Effects of Nb addition on the formation and morphology of TiO2 nanotubes in Ti alloys, BP.IC
Abstract
The formation of a nanostructured TiO2 layer in components based on titanium alloys is an efficient way to increase the chances of success in orthopedic and dental implant surgeries. The main objective of this research project is to evaluate the preparation of TiO2 nanotube layers on samples of Ti-Nb alloys. These alloys form the basis of Ti alloys already commercially used in orthopedi...
- Design and semisolid processing of High-Entropy Alloys based on the CrCuFeMnNi system, BP.PD
Abstract
Semisolid processing of alloys comprises a whole class of technological processes that exploits the thixotropic behavior exhibited by metals with globular microstructure. Thixoforming is one of them and involves partial melting of a raw material before the forming step. It offers many advantages over conventional manufacturing processes, such as less turbulence during mold filling, redu...
- Evolution of rolling and recrystallization textures in a Ti-35Nb-7Zr-5Ta alloy and its effects on the growth of TiO2 nanotubes, BP.PD
Abstract
The titanium and its alloys, despite being a relatively expensive class of metal, have important applications in the aerospace and medical industry. While its high specific strength makes them attractive in the aerospace field, where weight reduction is important, its excellent biocompatibility and great corrosion resistance make it a great choice for fabrication of orthopedic and denta...
- Phase transformations, microestructure and mechanical properties of new beta metastable Ti-Nb-Zr-Fe (TNZF) titanium alloys for biomedical applications, BP.DR
Abstract
During the last decade, rare and high melting point metals (Nb, Ta and Zr) have been widely used as alloying elements for biomedical titanium alloys, as pointed out in the TNZT-O (Ti-36Nb-2Ta-3Zr-0,3O wt.%) composition developed by Saito, 2003. These elements, however, are costly and difficult to process. The combination of low cost metals, such as Mn, Fe or Sn, with classical beta stab...
- Thixoforming of titanium alloys: application to Ti-Cu, Ti-Fe and Ti-Co systems, BP.DR
Abstract
The use of titanium and its alloys as structural materials has grown steadily in the last few years, which is due to the interesting combination of mechanical, chemical, physical and biomedical properties of this metal. The most intense increase in the industrial consumption of titanium is strongly limited by its cost, which is related not only to the difficulties of its refining, but m...

- Smart drug delivery system based on TiO2 nanotubes grown over a beta-type Ti medical alloy, BE.EP.PD
Abstract
Titanium and its alloys are known by their unique combination of properties, such as high specific strength, excellent corrosion resistance in aqueous media, and low elastic modulus. Titanium also presents good biocompatibility, given by the stable and inert titanium dioxide (TiO2) layer that spontaneously form on its surface. TiO2 can also grow in the form of nanotubes or nanowires on ...
- In situ microstructure observations of semisolid Ti alloys using laser-scanning confocal microscopy, BE.EP.DR
Abstract
There remains an interest in alternative Ti forming techniques due to issues associated with conventional forming processes. Typical issues associated with plastic forming and conventional casting may include: high tooling costs, high tooling wear rates, reactivity between Ti and the mold material, possible oxidation, and shrinkable. An approach addressing the abovementioned shortcoming...
- Fe-activated formation of pseudospinodal alpha phase in TiNbFe based alloys, BE.EP.DR
Abstract
In this project, we aim to investigate the pseudospinodal formation of alpha phase in Ti-Nb-Fe based alloys. The Ti-Nb-Fe ternary system is a relatively low cost system with potential for many future applications. Thermodynamic analyses suggest that properly designed compositions of this system should present homogeneous alpha phase formation when solution-treated and step-quenched to t...
- Effects of aging heat treatments on phase precipitation and mechanical behavior of Ti-30Nb-xSn beta metastable titanium alloys, BE.EP.MS
Abstract
Ti-Nb-Sn biomedical alloys have been recently developed as promising biomaterials due to their excellent biocompatibility, low elastic modulus and even superelasticity. These desirable properties are highly influenced by the stability of metastable phases such as the orthorhombic martensite (alpha"), which has low elastic modulus, and the precipitation of omega and alpha phases during a...
