A masstransport theory for interphase precipitation with application to vanadium steels

A mass transport theory is developed for interphase precipitationreactions in binary and pseudobinary systems where constant concentrations of solute are maintained at the interphase boundary. The theory presents exact solutions to the problem of diffusion-controlled growth involving the coupled motion of two boundaries. It is generally applicable to interphase precipitation in both solid-solid and solid-liquid systems. Aspects of the theory are discussed with reference tothe interphase precipitation reaction in model iron-carbon-vanadium alloys
