Implication

Compares electromagnetic attractive forming and electromagnetic repulsive forming in aluminum alloy tubes, revealing differences in material behavior and surface quality.

Key Points

The research aims to compare the effectiveness of electromagnetic attractive forming and electromagnetic repulsive forming in expanding aluminum alloy tubes.
Developed an efficient electromagnetic attractive forming approach for aluminum alloys.
Introduced an inner die and optimized coil current waveform and frequency.
Conducted experimental and simulation analyses to evaluate deformation behavior and microstructure.
EMAF samples showed more uniform wall thickness and better surface quality than EMRF samples.
EMRF resulted in fuller contour shapes but presented issues like wall thinning and orange peel surfaces.
Microstructural analysis revealed that EMRF induced significant grain refinement, while EMAF had less impact on grain size.
