Abstract
We investigated the wetting of bicrystals of pure copper and copper with iron enriched surface, molten lead, the morphology of the formed grooves, the liquid-metal etching was studied, the angles of wetting were determined, the surface factor g, which characterizes the ratio of the values of the surface tension of the grain boundaries and the interface of liquid and solid phases was calculated
