“…The LSV results demonstrated an interesting trend: as the α–β lath thickness increased, the value of I corr decreased. This observation aligns with previous research, which reported a decrease in current density with an increase in heat treatment temperature . This finding suggests that the presence of the α′-phase does not significantly affect the electrochemical properties of the Ti6Al4V alloy under static conditions.…”

Wire arc additive manufacturing (WAAM) holds promise for producing medium to large industrial components. Application of WAAM in the manufacturing of biomedical materials has not yet been evaluated. The current study addresses two key research questions: first, the suitability of the WAAMed Ti6Al4V alloy for biomedical applications, and second, the effect of Ti6Al4V’s constituents (α and β phases) on the cell viability. The WAAMed Ti6Al4V alloy was fabricated (as-deposited: AD) using a metal inert gas (MIG)-based wire arc system using an in-house designed shielding chamber filled with argon. Subsequently, samples were subjected to solution treatment (950 °C for 1 h), followed by aging at 480 °C (T1), 530 °C (T2), and 580 °C (T3) for 8 h and subsequent normalization to ambient conditions. Microstructural analysis revealed ∼45.45% of α′-Ti colonies in the as-deposited samples, reducing to 23.26% postaging at 580 °C (T3). The α-lath thickness and interstitial oxygen content in the sample were observed to be proportional to the aging temperature, peaking at 580 °C (T3). Remarkably, during tribocorrosion analysis in simulated body fluid, the 580 °C-aged T3 sample displayed the lowest corrosion rate (7.9 μm/year) and the highest coefficient of friction (CoF) at 0.58, showing the effect of increasing oxygen content in the alloy matrix. Cell studies showed significant growth at 530 and 580 °C by day 7, correlated with higher oxygen content, while other samples had declining cell density. Additionally, optimal metallurgical property ranges were identified to enhance the Ti6Al4V alloy’s biocompatibility, providing crucial insights for biomedical implant development.

“…Thus, the mechanism of corrosion resistance variation with normalizing heat treatment has been understood. Zhang et al [14] changed the brittleness of AlCoCrFeNi alloy via a normalizing heat treatment method to modify its mechanical properties. The result showed that normalizing heat treatment was better than quenching in water and this can increase the application of the high entropy alloy in a different environment.…”

The increasing demand for high entropy alloys and the need to develop high-strength steels for structural applications has led to the various applications of heat treatment in the metallurgical field. However, numerous mechanical integrities of heat treatment must be satisfied to ensure that the desired property is not only obtained but also achieved sustainably even while the material is under the application in a degraded environment. Thus, the study did an extensive review of the different heat treatment methods and their benefits. The study discussed the purpose of heat treatment, types of heat treatment, and their effect on the corrosion behaviour of the substrate. This provides potential information on the basics of heat treatment to further understand its impact on the corrosion performance of engineering materials.
