In this paper, the method of determining the phase boundary energy is briefly introduced. The mathematical formula of phase interface energy measured by the metallographic method is proved. The theoretical distribution curve of the dihedral angle is given and compared with the actual measurement curve. The results show that it is an easy and accurate method to determine the phase interface energy of the alloy by the metallographic method.
