摘要：
The effect of rare earth element yttrium on the high temperature oxidation resistance of a directionally solidified Ni-base superalloy was studied with scanning electron microscopy (SEM), energy dispersive spectrum (EDS) and X-ray diffraction (XRD) techniques. The results show that the oxidation resistance of the alloy is substantially improved by adding proper amount of yttrium.
