The crystal structure of the platelet phase and its orientation relationship with the matrix have been determined using transmission electron microscopy, convergent beam electron microscopy, X-ray energy dispersive spectrum, X-ray diffraction analysis and high resolution transmission electron microscopy. It has a CaCu5 type crystal structure (space groupP6/mmm) with lattice parameters a=0.498 nm and c=0.408 nm. The crystallographic orientation relationship between the phase and the matrix is found to be (111)γ Key words:  Fe-Ni-Co base superalloy      rare earth element      crystal structure      Received:  18 April 1998      Service E-mail this article Add to citation manager E-mail Alert RSS （） Articles by authors URL:  https://www.ams.org.cn/EN/     OR     https://www.ams.org.cn/EN/Y1998/V34/I4/367 1 Smith D F, Clastworthy E F, Tipton D G, Mankins W L.
