WebIn an incoherent boundary, there is no regularity of lattice-plane matching across the boundary, i.e., there is no coherent boundary, as illustrated in Fig. 13.5 (b). This is a large angle boundary, between the precipitate and the matrix, i.e., normal interface boundary. The formation of semi-coherent boundary is illustrated in Fig. 13.4. Web2 days ago · In Eqn. 8, n c * is the number of atoms in the embryo of critical size which can be estimated from r c * and β c is the jump frequency of atom transfer across the incoherent boundary for the growth of an embryo which can be estimated from the GB diffusion data [62]. A detailed account of these parameters is given in the Supplementary Material.
