Abstract. To address the issue of incomplete formation of low necking coefficient pipe fittings in hot extrusion processes, this study adopts a novel three-roll skew rolling (TRSR) technique to investigate the microstructural recrystallization distribution patterns during necking forming of aerospace thin-walled pull rods using TRSR. The principles of TRSR necking forming of pipe fittings are initially elucidated, followed by the establishment of a finite element model using simufact forming software and secondary development of the software to embed dynamic recrystallization volume and grain size models. The study analyzes the temperature distribution patterns and dynamic recrystallization behavior during necking forming of aluminum alloy thin-walled pipes via TRSR, aiming to contribute to the research on high-quality necking pipe fittings produced through TRSR.
