Abstract

Wire Arc Additive Manufacturing (WAAM) is a cost-effective technique for fabricating components from the Ti-6Al-4V alloy, known for its high strength and utility in demanding applications. To maximize its strength, the alloy undergoes Solution Treating and Aging heat treatment, comprising three key steps: (i) Solution Treating: The alloy is heated to 950°C (just below the β transus) and held for 1 hour, increasing the β phase proportion. This step sets the foundation for further strengthening in subsequent stages. (ii) Quenching: Rapid cooling in water preserves the β-favored phase from solution treatment. Without rapid cooling, the material would revert to a higher α phase content upon slow cooling. However, this quenching process can introduce residual stresses and unstable structures, like martensite. (iii) Aging: The alloy is held at 530°C for 8 hours, decomposing residual martensite and unstable β phase into stable α and β phases. This controlled transformation enhances the alloy’s mechanical strength, by up to 3.13%.
