The goal of this proposal is to investigate physical metallurgy and additive manufacturing of titanium alloys aiming to produce structural materials with graded properties. Ti and its alloys exhibit a wide range of interesting properties, particularly high mechanical strength-to-weight ratio, high corrosion resistance and unique biocompatibility. Their mechanical behavior depends directly…

Metastable beta Ti alloys are applied in a number of sectors and obtained when enough beta stabilizer contents are added to Ti, which leads to a decrease in the beta transus temperature, shifting the martensitic transformation start temperature to below room temperature. When solution heat treated at high temperatures and rapidly cooled, they show metastable retained beta phase combined w…
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 a…

Additive manufacturing is an effective route for processing Ti alloys and producing materials with functional gradients. An interesting system for obtaining orthopedic biomaterials refers to Ti-Nb-Fe-Sn. In this system, Nb promotes the beta phase stabilization, Fe allows an increase in mechanical strength and Sn reduces the omega phase precipitation. This work aims to evaluate the effect …
Ti and its alloys allow the manufacturing of components with stiffness gradient, which can be obtained in parts with or without composition gradient. Among the Ti alloys, the Ti-13Nb-13Zr alloy is widely used in the manufacturing of orthopedic implant devices. In this alloy, Nb is the main beta stabilizing element, while Zr acts as a metastable phase suppressor. After solution and quenchi…

Titanium alloys, when solution treated at high temperatures in the beta field and rapidly cooled to room temperature, exhibit microstructure made up of metastable beta phase and nanometric precipitates of omega phase, and have reduced mechanical strength and low elastic modulus. Mechanical strength of these alloys can be increased by means of aging heat treatments carried out at intermedi…
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 orthopedic …
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, reduce…

Multicomponent alloys usually applying several elements in equiatomic or near-equiatomic ratios are a recent new class of metallic materials, being commonly referred to as high entropy alloys (HEAs) in the literature. There is an enormous variety of compositions and microstructures that can be explored, leading to the same diversity of mechanical and physical properties. Among them, eutec…
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 th…
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 shortcomings …
