Layer growth additive effects

In Chapter 7 various growth models were described layer growth (Section 7.9), nucleation-coalescence growth (Section 7.10), development of texture (Section 7.11), columnar microstructure (Section 7.12), and other structural forms (Section 7.13). In this section we discuss the effects of additives on these growth mechanisms. 

In this book, attention will only be paid to the parallel-plane layers whose thickness is the same over the entire surface of contact of the reactants. In addition, the length of the layer in the direction normal to the direction of diffusion of components A and B (see Fig. 1.1) is assumed to be considerably greater than its thickness. In this case, the edge effects on the process of layer growth can be neglected.
