摘要： PROBLEM TO BE SOLVED: To provide a titanium sheet having remarkably improved formability.
SOLUTION: In the hexagonal system titanium sheet, the Kearns factor f value defined by equation (1) and the like is controlled to ≥0.60. β represents an azimuth (ND direction, 0°; RD-TD plane direction, 90° (π/2)) formed by the normal of the (0001) face of a hexagonal Ti crystal and the normal of a rolled surface. Vβ represents the volume ratio of crystal grains satisfying the angle β (the ratio to the volume of all the hexagonal Ti crystals (this entire volume is determined as 1)).

摘要： PROBLEM TO BE SOLVED: To produce an Al-Mg-Si based alloy sheet whose formability for pressing (especially formability for deep drawing, formability for bulging, and workability for bending) are more excellent than those of an existing Al-Mg-Si based alloy sheet specified under JIS6000 series. SOLUTION: An improved formability for pressing matched for press-forming is given by controlling, in accordance with a type of press-forming, at least the orientation density of a Cube orientation for an integrated structure of an Al-Mg-Si based alloy sheet. For example, an Al-Mg-Si based alloy sheet with an improved formability for deep drawing is provided when the ratio of an orientation density of S-orientation to that of a Cube orientation (S/Cube) is given as 1 or greater, and the ratio of an orientation density of Goss- orientation to that of a Cube orientation (Goss/Cube) is given as 0.3 or smaller, and crystal grain sizes are given as 80 μm or smaller.
