摘要：

The present work evaluates the growth kinetics of Fe2B iron boride forming on iron substrate by means of a diffusion model in the temperature range 1223-1323 K. The model takes into account the effect of the boride incubation time during the formation of Fe2B phase. The parabolic growth constant at the (Fe2B/Fe) interface and the mass gain generated by this treatment were estimated. Likewise a simple relationship was proposed to describe the variation of the parabolic growth constant as a function of both the temperature and the boron content in the Fe2B phase. Furthermore, the simulation results show a good agreement with our experimental results. (C) 2009 Elsevier B.V. All rights reserved.
