Abstract:

A study was made of the effect of remelting in an arc vacuum furnace on the properties of a heat-resistant nickel-base alloy. The alloy possesses high heat resistance but not sufficient plasticity. Conclusions 1 It is possible to obtain ingots without surface defects in an arc vacuum furnace the volume of the shrinkage cavity is considerably reduced in ingots produced in an arc vacuum furnace there are no sub-skin porosities, scabs, or laps 2 remelting in an arc furnace ensures a decrease in the C, S, O, and N content in the alloy 3 the nonmetallic inclusions are markedly reduced in an alloy melted in an arc vacuum furnace the inclusion particles are finer and are uniformly distributed through the volume of the metal and 4 remelting in a vacuum ensures increased tensile strength of an alloy and improvement of its plasticity.
