The effect of rare earth(RE) oxide on impact toughness and primary structure of surfacing metal was investigated . The results show that the impact toughness of surfacing metal containing RE oxide can be increased by 50 %. The primary structure can be refined and its shape changed from columnar crystals to equiaxed ones. 展开更多

The oxygen isotope fractionation equations are calculated for major rare earth oxide minerals by using an increment model. The effects of the variation of RE composition, the isomorphic replacement of Ti 4+ , Nb 5+ , Ta 5+ , and Th 4+ and the metamictization on the oxygen isotope fractionation in minerals are also discussed. The rare earth oxides are not applicable for geothermometry due to their changeable oxygen isotope fractionation coefficients. 展开更多
