Title (EN) TITANIUM MATERIAL FOR HOT ROLLING
(FR) MATÉRIAU DE TITANE POUR LAMINAGE À CHAUD
(JA) 熱間圧延用チタン材
Abstract:
(EN) Provided is a titanium material for hot rolling that has a base metal 1b made from an industrial pure titanium or a titanium alloy, and a surface layer 1a that is formed on at least one rolling surface of the base metal 1b and has a chemical composition that is different from that of the base metal 1b. The thickness of the surface layer 1a is 2.0-20.0 mm and accounts for at most 40%, per side, of the total thickness. Regarding the elements included in the surface layer 1a but not included in the base metal 1b, when the contained amount of an element included in the surface layer 1a is measured at multiple points, the relationship |CAVE-C0|/CAVE×100 is at most 40%, where CAVE is the average amount of the increase in the contained amount from the base metal 1b, and C0 is the amount of the increase in the contained amount from the base metal 1b at each measurement location. The chemical composition of the surface layer includes at least one of Si, Nb, Ta, and Al as an element for which there is an increase in the contained amount from the base metal. The titanium material for hot rolling has a desired oxidation resistance despite being inexpensive.
(FR) L’invention concerne un matériau de titane pour laminage à chaud (1) qui est équipé : d’un matériau de base (1b) constitué d’un titane industriel pur ou d’un alliage de titane ; et d’une partie couche superficielle (1a) qui est formée sur au moins une face de laminage du matériau de base (1b), et qui possède une composition chimique différente de celle du matériau de base (1b). Ladite partie couche superficielle (1a) présente une épaisseur comprise entre 2,0 et 20,0, et une proportion par rapport à l’épaisseur totale inférieure ou égale à 40% par face. Lorsque la teneur en éléments chimiques contenue dans la partie couche superficielle (1a) est mesurée en une pluralité de points, pour les éléments chimiques non contenus dans le matériau de base (1b) parmi ceux contenus dans la partie couche superficielle (1a), le rapport entre une valeur moyenne CAVE d’une teneur ajoutée au matériau de base (1b) et la teneur ajoutée C0 au matériau de base (1b) en chaque endroit de mesure, est tel que |CAVE-C0|/CAVE×100 est inférieur ou égal à 40%. La composition chimique de ladite partie couche superficielle (1a) contient, en % en masse, au moins un élément choisi parmi Si, Nb, Ta et Al, en tant que teneur ajoutée au matériau de base (1b). Ce matériau de titane pour laminage à chaud (1) possède la résistance à l’oxydation requise indépendamment de son bas coût.
(JA) 工業用純チタンまたはチタン合金からなる母材1bと、母材1bの少なくとも一方の圧延面に形成された母材1bとは異なる化学組成を有する表層部1aと、を備え、表層部1aが、その厚さが2.0~20.0mm、全厚さに占める割合が片面あたり40%以下であり、表層部1aに含まれる元素のうち母材1bには含まれない元素について、表層部1aに含まれる元素の含有量を複数点測定したとき、母材1bからの増加含有量の平均値CAVEと各測定箇所における母材1bからの増加含有量C0との関係:|CAVE-C0|/CAVE×100が40%以下である、熱間圧延用チタン材1。前記表層部の化学組成は、母材からの増加含有量として、質量%で、Si、Nb、TaおよびAlから選択される一種以上を含む。この熱間圧延用チタン材1は、安価にも関わらず、所望の耐酸化性を有する。
