A TECHNIQUE FOR THE EVALUATION OF HYDROGEN EMBRITTLEMENT.

Abstract

Membranes of Armco iron, zone-refined iron and Vescoget H-ll steel were used. Premeation measurements were made in various ambients at a current density of 8.1 mA/sq cm. In the hysteresis experiments the membranes were mounted on a Dillon tester and when permeation reached a steady state, stress was applied. This was repeated several times apply increasing stresses. After permeation had been determined at the highest stress (35,000 psi), the procedure was reversed, i.e. permeation was determined at various decreasing stresses. (Author)
