摘要：
On the interface of diffusively bonded Fe-16Al and Q235, we observe the formation of a well-pronounced layer formed by FeAl, Fe3Al, and alpha-Fe (Al) solid solutions. This layer can decrease the diffusion activation energy (facilitating the diffusion of elements and, hence, accelerating its growth). The formation of the diffusion layer is preceded by a latent period and its thickness x increases with time according to the parabolic law: x(2)=4.8(.)10(4) exp[-133,020/(RT)](t-t(0)).
