Abstract
The destructive influence of internally nucleated growing crystallites upon the growth of an oriented crystal front is examined. In particular, a simple two-dimensional model system is used to study the interaction of an oriented, planar growth front with a particle, initially of negligible size, which grows by circular growth. The locus of the intersection points of the fronts is obtained and used to derive an expression for the misoriented (ruined) area fraction produced by the presence of the growing particle. It is demonstrated that the reduced ruined area fraction is a function of two controlling parameters that describe the relative growth velocity of the interfering particle and its relative nucleation position. The sensitivity of the reduced ruined area fraction to these controlling parameters is ascertained and discussed.
