摘要: 本文研究了添加0.1%和0.5Wt%钇对 M38′合金氧化行为和机构的影响。试样在大气中1000℃氧化100hr。实验结果表明,加入0.1%钇的合金,其氧化速率比不加钇合金有明显的降低;将合金中钇含量增加到0.5%,其氧化速率略有增加。三种合金的氧化动力学基本遵从抛物线规律。当氧化70hr 后,不加钇合金的氧化速率向较快方向变化。金相观察到不加钇合金形成一个内氧化带,而含钇乙合金基体内不再产生内氧化。

Abstract：The effect of additions of 0.1%Y and 0.5%Y to M38' alloy on the oxidation behavior and mechanism was studied on samples exposed in air at 1000℃ for 100hrs.The results obtained indicated that the oxidation rate of the alloy with 0.1%Y was lower than that of the alloy without Y,while further increase of Y content to 0.5% increased the oxidation rate only slightly. However,the oxidation rates of all these three alloys obeyed a parabolic rate law.The oxidation rate of alloy without Y increased rapidly after exposure of 70hrs. The observed results from optical micrographs showed there was internal oxidation zone in the alloy without addition of yttrium,oxidized at 1000℃ for 100hrs,but internal oxidation did not appear in alloys with addition of yttrium.
