Abstract (en)

[origin: WO2011162713A1] The present invention relates to a metal base alloy and to methods for producing the alloy. The metal base alloy product consists of the formula Mebase Ta Sib Crc Mnj Ve Cf, wherein - Mebase is a metal base selected from the group consisting of Fe, Co and Ni, in an amount ranging from about 45-75 w%, - Ta is an alloying material selected from the group consisting of Mo, Nb and Ta in an amount a ranging from about 5-10 w%, - Sib is a further alloying member in an amount b ranging from about 4-10 w%, - Crc is a further alloying member in an amount c ranging from about 8-30 w%, - Mnd is a further alloying member in an amount d ranging from about 0-10 w% - Ve is a further alloying member in an amount e ranging from about 0-10 w%, and - Cf is a further alloying member in an amount f ranging from about 2-4 w%. The metal base alloy product contains a substantially homogenous dispersion of separate precipitated carbide particles in an amount ranging from 10-65 percentages by volume and the precipitate carbide particles have an average diameter of 0.01-5 micrometers.
