Physical metallurgy of austenitic iron - nickel - chromium - aluminum alloys

The physical metallurgy of the high aluminum (4-5%) austenitic Fe-Ni-Cr alloys has been studied. These alloys have been found to have an extraordinary oxidation resistance comparable or superior to the presently available commercial alloys in the temperature range of 800;The peak age hardening precipitate in low chromium alloys (10% Cr) has been identified as gamma prime (Ni;A minimum of 10% chromium has been found to be required in these alloys to maintain a continuous Al...
