Two step nucleation
WebThe most significant of these is the two-step mechanism of nucleation, according to which the crystalline nucleus appears inside pre-existing metastable clusters of size several … Weba2 (2) Where, D Al is the diffusion coefficient of Al along dislocations. As the diffusivity of Al is lower than that of N, diffusion of Al is assumed to be the rate controlling step for precipitation. Since the precipitates are nu-cleated on dislocations, the nucleation and growth of particles are greatly influenced by pipe diffusion through
