N2 - Rotary swaging is a process usually applied to reduce the entire or local diameter and size of rods and 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.
