The caculations of attachmemt energy of each F face show that{111} are most important faces. It has also inferred that one of the growth unitsof MC carbides may be octahedrol molecula which consist of a metal atom sur-rounded by an octahedron of six carbon atoms. The attachment scheme of octahedralunits onto crystal should be layer grdwth mechanism on the {111} faces.
