Process for producing high-temperature creep-resistant nickel alloys in an electron beam furnace

摘要

It is the object of the invention to alloy the highly reactive alloy elements Al, Nb, Ti, Zr, Mg, B and cerium mixed metal homogeneously in vacuo and at the same time to exploit the cleaning action of these elements for the melt and their action in improving the creep resistance. According to the invention, this is achieved by alloying 1 to 6 % by weight of pure titanium and/or 0 to 8 % by weight of pure niobium and also 0.2 to 6 % by weight of aluminium in the form of an aluminium-magnesium alloy with a base alloy so that magnesium is also present in a homogeneous distribution in addition to titanium, niobium and aluminium.
