Explanation

A kind of compound formed by carbon and other elements (mainly transition elements) is one of the important constituent phases in alloy (especially general steel). Most of the elements that form compounds with carbon have an unfilled d d electron layer in their atomic structure, and the more dissatisfied the d electron layer is, the greater the affinity between the elements and carbon will be, and the carbide formed will be more stable. carbide should be classified as interstitial phase according to its crystal structure“
