Fe-20Cr-4Al-S(185ppm)合金の酸化挙動に及ぼす微量Y添加の効果 The effects of yttrium addition on oxidation behavior of a Fe-20Cr-4Al-S (185ppm) alloy
The effects of yttrium addition on oxidation behavior of a Fe-20Cr-4Al-S alloy were studied in dry air at 1273K for 3600ks by mass change measurements, macro-morphology of oxidized surface, X-ray diffraction and scanning electron microscopy. Mass change of an alloy containing only S (185ppm) was 0.67×10<sup>-2</sup>kg/m<sup>2</sup>. The mass change of the alloys increased in the order of the 300ppmY<800ppmY<3700ppmY<10ppmY<185ppmS.
