Here VF(a,/0) is the (3 a transition probability for which we accept the conventional "thermally activated atomic exchange model . Below we briefly review several recent works on the general formulation of this approach and on its applications to studies of alloy phase transformations.

SCC in alloys is controlled by the alloy sohd solution composition, grain boundary segregation, alloy phase transformation, duplex structure, and cold work. SCC metallurgy is discussed in detail in Chapter 9.

In metal alloys, phase transformations and preeipitations at the grain boundaries are generally surface phenomena (on the surface of the grains) and do not apparently rise from the phenomena of nucleation in the bulk. However, if the grains are sufficiently numerous and about the same dimensions, we can make the approximation of a representation in volume of the grain boundaries, which are considered as potential sites. If these sites are located at random, it is possible to apply the whole of the volume of the alloy to the preceding models of Avrami and Erofeev, which one regularly finds in the literature (often without justification).

Antimony additions of 1 % to eutectic Sn-Ag have little or no effect on the melt temperature. It is believed that at this low level, the eutectic Sn-Ag alloy phase transformation still dominates. However, a 3% Sb addition to eutectic Sn-Ag causes the liquidus temperature to increase from 221°Cto 225°C[46j.
