José Rodolfo Galvele
José Rodolfo Galvele, Argentine metallurgist (Buenos Aires 10 March 1937 – Buenos Aires 31 July 2011) Authored one book and more than 160 papers Found that aluminum suffered from intergranular corrosion with hydrogen bubbles diffusing along grain boundaries and also showed that alloying elements eliminated molecular hydrogen improving the corrosion resistance of aluminum in his Ph.D dissertation (1962) A methodology for the prediction of susceptibility to stress corrosion cracking (1976) Proposed a simple model to explain pitting corrosion mechanism or acid induced pit stabilization theory (1976-84) Proposed a famous mechanism of stress corrosion cracking or surface mobility mechanism known as Galvele model (1986-7) With G.S. Duffó developed an equation for the calculation of the surface mobility coefficient based on exchange current density SOME BIBLIOGRAPHY With C.M. Giordano, S.B. Farina & G.S. Duffó.
