An iron-based sintered powder metal article for cam lobe and other high temperature, high wear applications requiring excellent net-shape stability during sintering comprises a powder metal mixture consisting essentially of, by weight, 0.5 - 3.0% Mo, 1 - 6.5% Cr, 1 - 5% V, and the balance Fe and impurities. These articles also have a carburized case having 0.7 - 1.2% C by weight. Following carburization of the case, the articles are quenched to form a martensitic matrix having a network of disbursed carbides of Cr and V. The resulting sintered articles have good mechanical strength and wear resistance and possess excellent machineability and dimensional stability.

L'invention concerne une poudre métallique frittée à base de fer pour lobes de came et autres applications haute température et haute usure, nécessitant une excellente stabilité de cote finale en cours de frittage, qui est un mélange de poudre métallique comprenant essentiellement, en poids : 0,5 3 % de Mo, 1 6,5 % de Cr, 1 5 % de V, et pour este Fe et impuretés. Ces produits présentent en outre une enveloppe cémentée comprenant, en poids, 0,7 1,2 % de C. Une fois réalisée l'enveloppe cémentée, on trempe les produits pour établir une matrice martensitique à réseau de carbures dispersés de Cr et de V. Les produits frittés résultants ont une bonne résistance mécanique et une bonne résistance à l'usure, et ils possèdent une excellente stabilité d'usinage et dimensionnelle.
