Further Observations on the Effect of Grain Boundary Segregation in the Hydrogen Embrittlement of Nickel.

Abstract

Earlier work has shown an association between the intergranular embrittlement of nickel by hydrogen and the presence of hydrogen recombination poisons at the grain boundaries. The present effort demonstrates that the susceptibility of nickel to embrittlement may be controlled by heat treatment sequences which affect the partitioning of impurities. It is also suggested that the association between impurities and microchemistry may apply in part as well as to the temper embrittlement of steels. (Author)
