Definitions
- Resistance materials of the kind specified may be divided into three principal classes:
- This grain boundary oxidation will decrease the utility of the material as a resistance alloy, due in part to the fact that the oxidation will change the electric resistance value of the alloy, and in part to the fact that the grain boundary oxidation causes the body of the material to grow and thus to change its dimensions. Therefore, if it were possible to reduce the tendency towards grain boundary oxidation, this would enable the quality of the material to be materially improved, particularly owing to the fact that the maximum operating temperature could be increased.
- the quantity of rare-earth metals added to the alloy may be in the form of so-called misch metal containing approximately to cerium, 22 to 25% lanthanum, 15 to 17% neodymium and 8 to 10% of other rareearth metals. It is understood, however, that other alloys of rare-earth metals, or such metals uncombined, may also be used, as well as oxides of such metals in combination with a reducing agent adapted to transform the oxides into a free metallic state.
- nickel-chromium type It is practical in the production of resistance alloys of the nickel-chromium type to add metals adapted to cause deoxidation and outgassing of the alloy, such as manganese, aluminium, zirconium, magnesium and calcium, as well as carbon stabilizing metals such as vanadium, titanium, columbium and tantalum. Further there will usually be a certain amount of cobalt present in the nickel as an impurity.
- the expression balance nickel as used hereinafter is to be interpreted as including the presence of the above-mentioned metals separately or in any combination and in percentages of the order of fractions of 1%.
- compositions alloyed in accordance with the present invention may be mentioned:
- a nickel-chromium alloy containing to 30% chromium, 0.2 to 2% silicon and 0.01 to 0.5 rare-earth metals, and further characterized by containing, in its finally produced condition, traces of boron amounting to a maximum content of 0.02%, and the balance nickel.
