Abstract: MA 6000 is a mechanically alloyed Ni-based ODS-type alloy. Excellent high temperature strenght makes it a strong candidate for application in high temperature industrial processes. In order to assess its usefulness for high temperature structural components, an indepth knowledge of its oxidation behaviour including in particular long term exposure is necessary.Tthe present work deals with studies of the cyclic ans isothermal oxidation of MA 6000 in the temperature range of 900-1050*C with emphasis on 1050*C. A few complementary studies have been carried out on the oxide integrity under creep conditions for exposure times of up to 11000 h. The results have shown that oxidation of MA 6000 involves rather complex mechanisms and alterations of the oxidation behaviour still occurr after long term exposure. Excellent oxidation resistance is based on the formation of an internal continuous Al2O3 layer.
