Влияние кинетики сегрегации на распределение зернопограничной примеси

2003 
A solute segregation from a grain of a finite size into its boundary was first studied analytically. The general case was considered when mass transfer is due both to diffusion of «free» unbounded solute atoms, and to solute atoms bounded in complexes with vacancies. Also, general equations were obtained in for the case, when different solute atoms are present. The conditions were determined when the concentration of one of the solute atoms reaches transiently a maximum.
