Abstract
(EN)
Provided are a titanium plate endowed with excellent strength and moldability, as well as a plate for a heat exchanger and a separator for a fuel cell in which said plate is used. A titanium plate containing Fe and O, and including an α-phase crystal grain structure that is an HCP structure, wherein when: the crystal orientations of the α-phase crystal grains are represented by a crystal orientation distribution function; ϕ1=0°, Φ=35°, and ϕ2=0° represent orientation 1; ϕ1=0°, Φ=35°, and ϕ2=30° represent orientation 2; ϕ1=90°, Φ=50°, and ϕ2=0° represent orientation 3; ϕ1=90°, Φ=50°, and ϕ2=30° represent orientation 4; ϕ1=50°, Φ=90°, and ϕ2=0° represent orientation 5; and the area ratio of crystal grains having orientations within 15° centered on these orientations with respect to the total area of all of the α-phase crystal grains are denoted respectively as X1, X2, X3, X4, and X5, then 0.05 ≤ (X3 + X4 + X5)/(X1 + X2) ≤ 3.0, the average value of the equivalent circular diameter of the α-phase crystal grains being 3-25 μm, and the maximum value being 140 μm or less.

L’invention porte sur une plaque de titane pourvue d’excellentes résistance et aptitude au moulage, ainsi que sur une plaque pour un échangeur de chaleur et un séparateur pour une pile à combustible dans lesquels ladite plaque est utilisée. La plaque de titane selon la présente invention contient du Fe et du O et comprend une structure de grains cristallins en phase α qui est une structure HCP. Lorsque les orientations cristallines des grains cristallins en phase α sont représentées par une fonction de distribution d’orientation cristalline ; Φ1 = 0°, Φ = 35° et Φ2 = 0° représentent l’orientation 1 ; Φ1 = 0°, Φ = 35° et Φ2 = 30° représentent l’orientation 2 ; Φ1 = 90°, Φ = 50° et Φ2 = 0° représentent l’orientation 3 ; Φ1 = 90°, Φ = 50° et Φ2 = 30° représentent l’orientation 4 ; Φ1 = 50°, Φ = 90° et Φ2 = 0° représentent l’orientation 5 ; et les proportions surfaciques des grains cristallins ayant des orientations à moins de 15° de ces orientations par rapport à la surface totale de tous les grains cristallins en phase α sont désignées respectivement X1, X2, X3, X4 et X5, alors 0,05 ≤ (X3 + X4 + X5)/(X1 + X2) ≤ 3,0, la valeur moyenne du diamètre de cercle équivalent des grains cristallins en phase α étant de 3 à 25 µm et la valeur maximale étant inférieure ou égale à 140 µm.
