| 摘 要： | Hot corrosion behavior of Ti-48Al-2Cr-2Nb alloy in molten salt environment of 75%Na_2SO_4 and 25%NaCl(mass fraction) at 800℃was studied using oxidation kinetics analysis,scanning electron microscopy,X-ray energy dispersive and X-ray diffraction analyses.The inter-phase selective corrosion,which caused the corrosion pits initiated from lamellar interfaces and the preferential corrosion ofα_2 phases,was observed during the hot corrosion of the alloy.The common controls of thermodynamic and kinetics in corr...
