Effect of nickel on hydrogen permeation in ferritic/pearlitic low alloy steels – Publication.

April 26, 2018 by Mariano Iannuzzi

This is the first of a series of articles on the effect of nickel on the hydrogen embrittlement resistance of low alloy steels. In this paper, we investigated how nickel in solid solution in the ferrite phase affected hydrogen permeation.
