| Abstract: | After referring to the research carried out on composite specimens formed by lamellae of “reactive” metals embedded in a lead matrix, an attempt is made to apply the data obtained on penetration of attack into these lamellae to the real case of the anodic corrosion of several two-phase Pb---Sb and Pb---Ag alloys in the as-cast condition.To this end, a theoretical treatment of the effect of a “reactive” second phase on the stability of an alloy is presented. Emphasis is laid on the role which material disintegration may play, provided the second phase particles supply routes for a fast penetration of the localized attack into the alloy structure. |
