Abstract
Abstract NICKEL BASE ALLOYS CONTAINING ADDITIONS OF ALUMINUM, CHROMIUM AND SILICON ARE DESCRIBED WHICH EXHIBIT A UNIQUE AND ADVANTAGEOUS COMBINATION OF HIGH TEMPERATURE MECHANICAL PROPERTIES AND RESISTANCE TO OXIDATION AT HIGH TEMPERATURES. IN PARTICULAR, THE OXIDATION RESISTANCE OF THE ALLOYS DESCRIBED IS SUPERIOR TO THAT OF PURE NICKEL AND OTHER HIGH NICKEL ALLOYS SUCH AS MIOINEL AND NICHROME WHICH ARE OLEFIN USED WHEREIN OXIDATION IS A PROBBLEM. THE OXIDATION RESISTANCE OF THESE ALLOYS IS A RESULT OF THE FORMATION OF A TENACEOUS OXIDE FILM CONSISTING ESSENTIALLY OF THE ADDED ALLOYING ELEMENTS.
