Abstract
The weight changes of alloys, based on nickel-chromium and nickel-iron-chromium oxidised in air for up to 1000 hours under cyclic temperature conditions have been determined and related to the microstructures of the alloys after exposure. Initial oxidation to form a protective scale occurred rather faster than predicted on the basis of isothermal oxidation data; subsequent spalling of the scale was reduced by high contents of nickel and chromium, and by minor additions of silicon, cerium and aluminium.
