Abstract
Anisotropy of the plastic properties is an index of sheet’s ability to stamping. In this work the transverse deformation coefficient and r-value were used. Uniaxial test was made for annealed pieces of 1 mm thickness from aluminum alloy AA2024, steel X10CrNiTi18-9, Titanium Grade 2 and titanium alloy Ti-2Al-1Mn. Pieces were cut at angle of 0, 22.5, 45, 67.5 and 90O to the rolling direction. Steel pieces have anisotropy coefficients practically independent from angle between it’s’ axis and the rolling direction. Pieces made of AA2024 cut at angle 45О to the rolling direction have largest anisotropy coefficients. Titanium alloys have the largest coefficients for angle 67,5О between axis of piece and the rolling direction. Both indexes of anisotropy are higher for titanium alloys, which is property of HCP-metals.
