Susceptibility to embrittlement by mercury and hydrogen was measured as affected by thermal treatment. Specimens were annealed at 900/degree/C and either quenched or furnace cooled. Fractures in air were ductile, and not affected by thermal treatment. Fractures of mercury-coated and hydrogen-charged samples were brittle and intergranular; elongation to fracture increased with increasing concentration of grain boundary phosphorus. 45 refs.
