Equilibrium grain boundary segregation levels have been measured on binary and ternary iron alloys with tin and sulphur over a wide temperature range, by means of two complementary techniques:… Continue Reading
The theory of equilibrium solute segregation at solid/solid interfaces can be approached usefully from classical surface/gas adsorption isotherms of varying complexity and encompassing both… Continue Reading
AbstractThe absolute surface energy of pure δ-iron as a function of nitrogen content within the solidsolubility range has been measured. The surface energy is significantly reduced, showing that… Continue Reading
AbstractSurface tension data at 1650°C have been measured for the Fe + S + O ternary system and the two binary systems, Fe + O and Fe + S using the levitated drop technique. The results indicate that… Continue Reading
ALTHOUGH it has long been appreciated that chemisorption is an anisotropic property of the crystalline substrate, few systematic studies have been reported. This communication reports a recent study… Continue Reading
Abstract Plasma disruptions in a fusion reactor will lead to high energy depositions for short times, which may cause melting of the wall. A comprehensive two dimensional transient computer model has… Continue Reading
