Fe-20Cr-4Al-S(185ppm)合金の高温酸化挙動におよぼす微量Hfの影響 Influence of small amount of Hf for oxidation of Fe-20Cr-4Al-S (185ppm) alloys
Oxidation behavior of Fe-20Cr-4Al-S (185ppm) alloys with hafnium was studied in dry air at 1273K for 3600ks by mass change measurements, macro-morphology of oxidized surface, X-ray diffraction and scanning electron microscopy. The mass change of the alloy containing only 185ppmS was of 0.67×10<sup>-2</sup>kg/m<sup>2</sup>. The mass changes of all the alloys increased in the order of the 900ppmHf<500ppmHf<1900ppmHf<185ppmS<4300ppmHf.
