The M 23 C 6, with M 6C as its nucleus and colatticed with M 6C, is on the grain boundary and grows in the form of thin lamellar and filmy single crystal. The misfit between M 23 C 6 and M 6C obtained from the moire pattern is about 3%.

• 而晶界上是以M6C为核并与之保持共格的M23C6，以薄片或薄膜单晶形式长大，从波纹图样上测得它们之间的错配度为3%25。
