DEFORMATION PROCESSING OF ANISOTROPIC METALS.
Abstract
Work was carried out primarily in two related areas: (1) further exploration of the planestrain deformation of the alpha (2.5 Sn - 5 Al) titanium alloy; (2) and the variation of plastic anisotropy with temperature and strain. One of the problems in an evaluation of plane-strain compression data is determining the friction-hill contribution to the measured load. Currently, plane-strain indentations are being made with a series of indentors of increasing width, Mos2 and 2-mil Teflon film are the lubricants. Other experiments have been based on plane-strain tension tests to avoid frictional complications. In this case plane-strain is enforced by milling a groove, across both faces of a strip specimen, at right angles to the loading axis; and producing a reduced section with a thickness of only 15% of that of the sheet, a length 4 times the thickness, and a width 40 times the thickness. Stress-strain curves from these samples are parallel to the compression curves and approximately 10% lower. (Author)
