Impact of solid-solution treatment on microstructural characteristics and formability of rotary-swaged 2024 alloy tubes

In this study, the effects of the rotary swaging process and subsequent softening heat treatments, namely full annealing and solid-solution treatment, are investigated. The results show that rotary swaging refines grain size, decreases the eutectic phase fraction, enhances mechanical strength, and decreases mechanical elongation. Solid-solution treatment enhances work hardening ability and improves uniform elongation, and is thus more suitable for enhancing the formability of rotary-swaged alloys. The factors that affect microstructural characteristics and mechanical properties are discussed.
