| Abstract: | Using rare earth as mlcro-aLloying element, RE alloys were added to purity steel. The effect of RE on the high temperature oxidation of purity steel was studied. The experimintal results show that the graihs of oxide are re.freed by adding RE, and the adhesion between oxidation layer and matrix is enhanced, thus, the high temperature oxidation of purity steel has obviously been improved. |
