摘要

The isothermal oxidation behavior of Haynes 230 alloy (Ni-Cr-W-Mo alloy) in air at 1100°Cwas investigated by means of SAXD and SEM (EDAX). The predominant phase in the oxide scales were Cr₂O₃ and (Ni, Mn, Cr)₃O₄. Multilayer was observed with increasing of oxidation time. The outer (Ni, Mn, Cr)₃O₄ scale may reduce the volatilization of inner Cr₂O₃ scale and its oxidation behavior almost followed parabolic law. Due to preferential diffusion of manganese and chromium, alloy composition beneath the oxide scale changed, which led to subsurface degradation such as intergranular oxidation, void formation, and no carbide zone formation.
