Progress in true-stress-true-strain testing is reported. It is estimatted that 35% area reduction at 850 deg F by wire drawing may be made between stress-relieving treatments. Preliminary investigation of cold compacting of canned powder followed by warm extruding to draw stock was carded wt. It was found that a critical compact green density exists which limits the swing point. Initial drafting experiments at 850 deg F were made. These indicate that large reductions in area per pass are more desirable that light reductions from the standpoints of surface and lubrication. (For preceding period see AD-210451.) (J.R.D.)
