“…Barriobero-Vila et al, have used this technique to study the effect of constant heating rates after solution treatment to gain further insight into phase transformations kinetics and formation of the equilibrium α-phase in the near-beta Ti-10V-2Fe-3Al (wt. %) alloy [141] and the near-beta Ti-5Al-5Mo-5V-3Cr-1Zr (wt. %) alloy [142].…”

“…In the case of the Ti-10V-2Fe-3Al (wt. %) alloy [141], the initial microstructure after super-transus solution treatment consists of metastable athermal ω-phase particles and orthorhombic α -martensite phase in a β-phase matrix. The authors illustrate that the α -martensite phase reverts to the β-phase and the magnitude depends on the heating rate.…”

Abstract:In this article, we provide a broad and extensive review of beta titanium alloys. Beta titanium alloys are an important class of alloys that have found use in demanding applications such as aircraft structures and engines, and orthopedic and orthodontic implants. Their high strength, good corrosion resistance, excellent biocompatibility, and ease of fabrication provide significant advantages compared to other high performance alloys. The body-centered cubic (bcc) β-phase is metastable at temperatures below the beta transus temperature, providing these alloys with a wide range of microstructures and mechanical properties through processing and heat treatment. One attribute important for biomedical applications is the ability to adjust the modulus of elasticity through alloying and altering phase volume fractions. Furthermore, since these alloys are metastable, they experience stress-induced transformations in response to deformation. The attributes of these alloys make them the subject of many recent studies. In addition, researchers are pursuing development of new metastable and near-beta Ti alloys for advanced applications. In this article, we review several important topics of these alloys including phase stability, development history, thermo-mechanical processing and heat treatment, and stress-induced transformations. In addition, we address recent developments in new alloys, phase stability, superelasticity, and additive manufacturing.

“…The amount of α" martensite formed in this study is nearly 2% higher than that formed after room temperature compression to 0.4 strain of the same Ti-10-3-3 alloy quenched from 725 • C [33,34]. This is despite the stability of β matrix deformed at 725 • C (near β transus temperature) being higher than that of β parent at room temperature [41].…”

A metastable-β titanium alloy, Ti-10V-3Fe-3Al (wt. %), was subjected to thermo-mechanical processing including the compression test at 725 • C, which is below the β transus temperature (780 • C), and at strain rate of 10 −3 s −1 . The presence of phases was determined using transmission electron microscopy and X-ray diffraction. Although the dynamic recovery took place together with slip, both deformation-induced α" martensite and ω were detected as other operating mechanisms for the first time in metastable-β titanium alloy deformed in α + β region. The volume fraction of stress-induced α" was higher than that of the same alloy deformed at room temperature due to a higher strain applied. Stress-induced twinning was not operational, which could be related to the priority of slip mechanism at high temperature resulted from thermally-assisted nucleation and lateral migration of kink-pairs.

“…Em outros estudos em que a transformação de fase em ligas β-metaestáveis também na condição inicial como-temperada foi explorada pela óptica da taxa de aquecimento, evidenciou-se que o aumento dessa taxa torna a distribuição das fases α'' e α mais homogênea ao longo da matriz β [6,[8][9][10][11], além de minimizar a precipitação durante o aquecimento. Em especial Ivasishin et al…”

The present Thesis is focused on the assessment of Ti-55531 alloy in situ solid state transformations during ageing at different temperatures as well as initial conditions. In this sense, the study emphasis will deal with both quantitative and qualitative analysis of the main constitutive phases found in the alloy, namely the body-centered cubic β, both hexagonal α and ω and the martensitic α", this one orthorhombic, by means of Rietveld refinement. Concerning the data, it was obtained by high energy x-ray diffraction (HEXRD) technique in a synchrotron light source facility. All the Debye-Scherrer rings resulting from these in situ experiments were analyzed by both FIT2Dand MAUD software.
