Abstract
Attempts have been made to predict loads in deep drawing Ti–6Al–4V, AISI 304, and Inconel X taking into account anisotropy and work-hardening characteristics. This has been accompanied by a comprehensive series of tests on these materials in different thicknesses (0.030–0.070 in.) using a variety of lubricants at room temperature. Draw-ability and agreement of predicted loads with those observed are seen to depend on a variety of factors. Most satisfactory agreement between prediction and observation is seen with the strongly anisotropic titanium alloy. Of the lubricants examined, polyethylene sheet and a molybdenum disulfide suspension in an acrylic resin appear to be most effective. Further work is proceeding on elevated temperature drawing.
