Abstract | An α+β type titanium alloy shaped material according to an embodiment of the present invention has a 0.2% yield strength of 830 MPa or higher, an elongation percentage of 10% or higher, a fatigue strength of 450 MPa or higher, and an acicular structure. The titanium alloy shaped material has a void area ratio of 1.0 x 10-5% or less, a torsion angle of ±3.0˚ or less from one end to the other end thereof, and a warp height (mm)/total length (m) of ±2.17 or less.
Un matériau formé en alliage de titane de type α+β selon un mode de réalisation de la présente invention possède une limite d'élasticité à 0,2 % de 830 MPa ou plus, un pourcentage d'allongement de 10 % ou plus, une résistance à la fatigue de 450 MPa ou plus, et une structure aciculaire. Le matériau formé en alliage de titane présente un rapport de surface de vide de 1,0 x 10-5 % ou moins, un angle de torsion de ± 3,0° ou moins d'une extrémité à l'autre de celui-ci, et une hauteur de chaîne (mm) / longueur totale (m) de ± 2,17 ou moins.
本発明の一態様に係るα+β型チタン合金形材は、0.2%耐力が830MPa以上、伸びが10%以上、かつ疲労強度が450MPa以上であり、針状組織を有し、ボイドの面積率が1.0×10-5%以下であり、一端から他端までの捩れ角が±3.0°以内であり、反り高さ(mm)/全長長さ(m)が±2.17以内である。 |
