Abstract

The effect of small amounts of yttrium (up to 1 wt. %) or hafnium (up to 1. 5 wt. %) on the oxidation behaviour of Co-Cr-Al alloys in the temperature range 1000-1200 degree C for times of up to 1000 h in air was studied. Both isothermal and cyclic tests were carried out; the cycle used consisted of 20 h at a high temperature after which the specimen was withdrawn from the furnace and was allowed to cool. The major part of the study was concerned with Co-10 wt. % Cr-11 wt. % Al alloys. Overall, hafnium additions appear to be preferable to yttrium additions. 19 refs.
