Abstract

Die Erfindung bezieht sich auf ein Verfahren zur legierungstechnischen Steuerung der Erstarrungskinetik und der Matrixzusammensetzung von karbidbildenden metallischen Schmelzen und auf einem vorzugweise nach dem Verfahren hergestellten Werkstoff mit hoher Härte, hohem Verschleißwiderstand und hoher Zähigkeit.The invention relates to a method for alloy control the solidification kinetics and the matrix composition of carbide-forming metallic melting and on a preferably by the process manufactured material with high hardness, high wear resistance and high Toughness.

Erfindungsgemäß ist vorgesehen, daß das Flüssigmetall in Abhängigkeit von dem Kohlenstoffgehalt und dem Gehalt an Elementen der Gruppe 5 des Periodensystems mit Aluminium in einer Konzentration von 0,3 bis 2,6 Gew.-% mit der Maßgabe legiert wird, daß Gew.-% Al = Gew.-% C x AN x F entspricht, wobei das Niobäquivalent AN aus AN = 0,3 + 0,1x Gew.-% V + Gew.-% Nb + 1,12 Gew.-% Ta und der Wirkungsbereichsfaktor F aus F = 0,7 bis 1,3 gebildet wird, worauf die Schmelze erstarren gelassen wird.According to the invention, the liquid metal is alloyed with aluminum in a concentration of 0.3 to 2.6% by weight, depending on the carbon content and the content of elements of group 5 of the periodic table, with the proviso that % By weight Al =% by weight C x AN x F corresponds, the niobium equivalent AN from AN = 0.3 + 0.1x wt% V + wt% Nb + 1.12 wt% Ta and the effective range factor F. F = 0.7 to 1.3 is formed, whereupon the melt is allowed to solidify.
