Abstract
The effect of pressure on the diffusion of zinc along a 43°<100> tilt grain boundary in an Fe-6at%Si alloy was investigated. Zinc penetrated into the grain boundary from a 100 µm thick liquid layer on the surface of the bicrystal. It was found that penetration of zinc causes a premelting phase transition in the grain boundary. The phase transition was suppressed for pressures higher than 0,5 GPa.
