Titane<\/h3>\n

Le titane est un m\u00e9tal de transition brillant avec une couleur argent\u00e9e, une faible densit\u00e9 et une r\u00e9sistance \u00e9lev\u00e9e.\u00a0Le titane est r\u00e9sistant \u00e0 la corrosion dans l’eau de mer, l’eau r\u00e9gale et le chlore.\u00a0Le titane peut \u00eatre utilis\u00e9 dans les condenseurs de surface.\u00a0Ces condenseurs utilisent des tubes g\u00e9n\u00e9ralement en acier inoxydable, en alliages de cuivre ou en titane selon plusieurs crit\u00e8res de s\u00e9lection (comme la conductivit\u00e9 thermique ou la r\u00e9sistance \u00e0 la corrosion).\u00a0Les tubes de condenseur en titane sont g\u00e9n\u00e9ralement le meilleur choix technique, mais le titane est un mat\u00e9riau tr\u00e8s co\u00fbteux et l’utilisation de tubes de condenseur en titane est associ\u00e9e \u00e0 des co\u00fbts initiaux tr\u00e8s \u00e9lev\u00e9s.

Vanadium<\/h3>\n

Le vanadium est un m\u00e9tal de transition dur, gris argent\u00e9, ductile et mall\u00e9able.\u00a0Le m\u00e9tal \u00e9l\u00e9mentaire se trouve rarement dans la nature, mais une fois isol\u00e9 artificiellement, la formation d’une couche d’oxyde (passivation) stabilise quelque peu le m\u00e9tal libre contre une oxydation suppl\u00e9mentaire.<\/p>\n<\/div>

Titane<\/a><\/h3>\n

Les deux propri\u00e9t\u00e9s les plus utiles du m\u00e9tal sont la r\u00e9sistance \u00e0 la corrosion et le rapport r\u00e9sistance\/densit\u00e9, le plus \u00e9lev\u00e9 de tous les \u00e9l\u00e9ments m\u00e9talliques.\u00a0La r\u00e9sistance \u00e0 la corrosion des alliages de titane \u00e0 des temp\u00e9ratures normales est exceptionnellement \u00e9lev\u00e9e.\u00a0Ces propri\u00e9t\u00e9s d\u00e9terminent l’application du titane et de ses alliages.\u00a0La premi\u00e8re application de production de titane remonte \u00e0 1952, pour les nacelles et les pare-feu de l’avion de ligne Douglas DC-7.\u00a0Une r\u00e9sistance sp\u00e9cifique \u00e9lev\u00e9e, une bonne r\u00e9sistance \u00e0 la fatigue et une bonne dur\u00e9e de vie au fluage, ainsi qu’une bonne t\u00e9nacit\u00e9 \u00e0 la rupture sont des caract\u00e9ristiques qui font du titane un m\u00e9tal pr\u00e9f\u00e9r\u00e9 pour les applications a\u00e9rospatiales.\u00a0Les applications a\u00e9rospatiales, y compris l’utilisation dans les composants structurels (cellule) et les moteurs \u00e0 r\u00e9action, repr\u00e9sentent toujours la plus grande part de l’utilisation des alliages de titane.\u00a0Sur l’avion supersonique SR-71, le titane a \u00e9t\u00e9 utilis\u00e9 pour 85% de la structure.\u00a0Gr\u00e2ce \u00e0 une tr\u00e8s grande inertie,<\/p>\n<\/div><\/div>\n<\/div><\/div>\n<\/div><\/div>\n

Vanadium<\/a><\/h3>\n

Le vanadium est principalement utilis\u00e9 pour produire des alliages d’acier sp\u00e9ciaux tels que les aciers \u00e0 outils rapides et certains alliages d’aluminium.\u00a0Le vanadium est g\u00e9n\u00e9ralement ajout\u00e9 \u00e0 l’acier pour inhiber la croissance des grains pendant le traitement thermique.\u00a0En contr\u00f4lant la croissance des grains, il am\u00e9liore \u00e0 la fois la r\u00e9sistance et la t\u00e9nacit\u00e9 des aciers tremp\u00e9s et revenus.\u00a0Le vanadium est ajout\u00e9 pour favoriser la r\u00e9sistance \u00e0 l’abrasion et produire des carbures durs et stables qui, n’\u00e9tant que partiellement solubles, lib\u00e8rent peu de carbone dans la matrice.\u00a0Le compos\u00e9 de vanadium industriel le plus important, le pentoxyde de vanadium, est utilis\u00e9 comme catalyseur pour la production d’acide sulfurique.\u00a0La batterie redox au vanadium pour le stockage d’\u00e9nergie pourrait \u00eatre une application importante \u00e0 l’avenir.<\/p>\n<\/div><\/div>\n<\/div><\/div>\n<\/div><\/div>\n
