Grain bound ary dif fu sion of cop per (GBD) in aluminum was investigated by EPMA in the temperature range from 300 to 400 graduate C. The triple product s delta Dgb (s – segregation co efficient, delta – grain boundary width, Dgb – GBD coefficient) was calculated using Fisher-Gibbs solution methods – by measuring of GB copper concentration as a functional penetration depth and the contour angle (at the top of diffusion wedge). In the first case s delta Dgb = S delta Dgb = 5.1ź10–11 m3 s źexp (-102 kJ/mol RT) and in the sec ond case S delta Dgb = 1.4ź10–11 m3 s źexp(-94 kJ mol RT).
