The static oxidation behavior of new nickel-based superalloy GH4065 Aat the temperature range of 650—750℃in air was investigated by isothermal static oxidation testing.The oxidation mechanism was discussed on the basis of oxidation kinetics and the analyses of oxidation product.The results show that GH4065 Aalloy characterizes with full oxidation resistance at the temperature range of 650-750℃,assessed by the indicator of average oxidation weight gain rate.The oxidation resistance performance of GH4065 Aall...
