Effect of the forming method on part shape quality in cold roll forming high strength Ti-6Al-4V sheet

High strength titanium alloy sheet, in particular Ti-6Al-4V, is used for structural applications; roll forming has been found to be an appropriate cold forming process for the manufacture of long components in Ti-6Al-4V. Roll forming Ti-6Al-4V at room temperature requires extensive FEA-assisted process development and optimisation to keep springback and part shape defects to a minimum. Currently the material behaviour of Ti-6Al-4V in the roll...
