Interface models of the matrix and Cr23C6. The part of the matrix is 36 atoms, colored as blue. There are three kinds of Cr23C6 part: Ase1 (38 Cr atoms +11 C atoms), Ase2 (38 Cr atoms + 12 C atoms) and Ase3 (42 Cr atoms + 12 C atoms). The atoms of Cr and C are colored as green and black respectively.
