Abstract

Surface and grain boundary wetting and penetration of pure Fe and a martensitic steel by Pb and Pb-Bi eutectic alloys were studied by the sessile drop and dispensed drop techniques at different temperatures (400–900°) and times (up to 30 h). By using two different atmospheres—high vacuum and a He-H2 gas—and different heat treatments, wetting was studied for both oxidized and deoxidized solid substrates.
