Abstract
A method that improves the formability of magnesium and magnesium tubes without altering the chemistry of such material or requiring changes to formation tooling. Magnesium or magnesium alloy sheet stock is subjected to at least one cycle of roll-forming deformation in a first direction followed by a reversal of roll-forming deformation and progressive development of a substantially circular cross-section. Lateral edges of the sheet are adjoined and the structure is thereafter heated above the recrystallization temperature.
