FIELD: metallurgy. ^ SUBSTANCE: plate from titanium or a titanium alloy with improved combination of stamping capability and strength includes a basic plate from titanium or a titanium alloy rolled in one direction, and a lubricant film applied onto surface of the basic plate from titanium or a titanium alloy. The lubricating film surface has a friction coefficient during sliding set as less than 0.15. The basic plate from titanium or a titanium alloy extends in rolling direction L (L-El) and Lankford value r in direction T, perpendicular to rolling direction (T-r), besides, L-E1 and T-r satisfy the following expression (1): (T-r)/(L-El)ëÑ0.07 (1). ^ EFFECT: plate has better combination of pressing capability and strength. ^ 10 cl, 5 dwg, 10 tbl, 5 ex |
