    Abstract: Refining elements for refining discs for disc refiners for the manufacture of mechanical pulp, for example, board pulp, are subjected to hard abrasive wear in acid environment and at high temperature. In order to improve the wear resistance alloys with precipitated carbides are used. A service life improved in comparison with known alloys is obtained with a refining disc with the following analysis in % by weight: 2.96 C, 0.77 Si, 0.82 Mn, 24.2 Cr, 5.16 V, 0.04 Ni, 0.03 Mo, and the remainder Fe and impurities. After casting, the refining segments are hardened and annealed and assume a hardness of 57-63 HRC.

    Abstract: The present invention is directed to an iron, aluminum, chromium, carbon alloy and a method of producing the same, wherein the alloy has good room temperature ductility, excellent high temperature oxidation resistance and ductility. The alloy includes about 10 to 70 at.% iron, about 10 to 45 at.% aluminum, about 1 to 70 at.% chromium and about 0.9 to 15 at.% carbon. The invention is also directed to a material comprising a body-centered-cubic solid solution of this alloy, and a method for strengthening this material by the precipitation of body-centered-cubic particles within the solid solution, wherein the particles have substantially the same lattice parameters as the underlying solid solution. The ease of processing and excellent mechanical properties exhibited by the alloy, especially at high temperatures, allows it to be used in high temperature structural applications, such as a turbocharger component.
