摘　　要：A method of improving the oxidation resistance of Cantor alloy through microstructure tailoring was revealed.Samples with distinctive microstructures were achieved by different annealing treatments on the cold-rolled Cantor alloy.Oxidation test was then carried out on the various annealed samples at 800°C for 24 h in air.The oxidation behavior was evaluated in terms of oxidation rate,surface and cross-section microstructure characterization.Although stratified oxide layers including outer Mn_(2)O_(3) and inner Cr_(2)O_(3) were observed in all the annealed samples,the thickness of Mn_(2)O_(3) and Cr_(2)O_(3) layers was different.Also,the samples exhibited different oxidation rates.The results indicate that the oxidation resistance of various annealed samples is closely related with grain size as well as twin density.
