On the kinetics of interface-diffusion-controlled peritectoid reactions

We consider the peritectoid reaction α+β→ω as it occurs at previously existing planar α/β interfaces, and at sufficiently low temperatures that volume diffusion is negligible and interphase boundary diffusion is rate-controlling. With the further assumption that the participating phases have fixed compositions and that the interfacial diffusion process is driven by gradients in interfacial curvature, we obtain a unique solution for the growth …
