| 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. |
