Title (EN) LOWER BAINITE ALLOY STEEL ARTICLE AND METHOD OF MAKING SAME
(FR) ARTICLE EN ACIER A FAIBLE TENEUR EN BAINITE ET SON PROCEDE DE FABRICATION
Abstract: front page image
(EN)A lower bainite alloy steel article particularly suitable for gears, bushings and the like includes carbon in the range of 0.60 to 0.80 Wt.% manganese in the range of 0.45 to 1.00 Wt.%, silicon in the range of 0.15 to 2.20 Wt.%, molybdenum in the range of 0.40 to 0.70 Wt.%, and the balance substantially iron. A process of heat treatment of the article includes the steps of quenching it from a first temperature at a preselected rate and of holding it at a second temperature for less than about two hours to complete transformation of the alloy directly from an austenite morphology to a substantially complete low temperature bainite morphology.
(FR)Un article en acier a faible teneur en bainite particulierement approprie pour les pignons, les coussinets et autres contient de 0,60 a 0,80% en poids de carbone, de 0,45 a 1,00% en poids de manganeser de 0,15 a 2,20% en poids de silicium, de 0,40 a 0,70% en poids de molybdene, le reste etant sensiblement du fer. Un procede de traitement thermique de l"article comprend sa trempe depuis une premiere temperature a une vitesse predeterminee et son maintien a une seconde temperature pendant moins de deux heures environ pour achever la transformation de l"alliage directement d"une structure austenitique a une structure bainitique sensiblement complete a basse temperature.
