Abstract
The hydrogen charging of AISI 316 stainless steel has turned unstable the austenitic structure which partially decomposes into two phases: {epsilon} (hexagonal close packed) and {alpha} ` (body centered cubic). A 1 N H{sub 2} SO{sub 4} solution was used as electrolyte, with varying concentrations of As{sub 2} O{sub 3} (0, 1, 5 and 100 mg/l) for a single constant applied current density (i{sub o} = 0,22 A/cm{sup 2}). It was observed that a smaller austenitic grain as well as a larger hydrogen charging time, improve the phase transformation. It was established that the order in which the transformation products of the austenite appear through hydrogen charging follows the sequence: Y {yields} Y-bar + {epsilon} {yields} Y + {epsilon} + {alpha} `, although there is still some doubt about the equivalent transformation order by plastic deformation.
