Cation Diffusion‐Mediated Displaced Reaction‐Transformation in Green Steelmaking

open access: yesAdvanced Science, EarlyView.
The removal of O lattice atoms by environmental H2 at the surface of Fe3O4 results in Fe enrichment, driving the inward diffusion of Fe cations into the bulk. Through hopping between unoccupied and initially occupied sites, cation diffusion triggers a spatially displaced reaction‐transformation and drives subsequent dynamic phase transformations and ...

STRAY CURRENT CORROSION OF STEEL

Naval Engineers Journal, 1976
ABSTRACTStray current corrosion has been of major concern to the Navy over the past few years. Serious corrosion attributable to stray current has occurred in seawater or brackish water on several occasions where the possibility of the corrosion having resulted from improper grounding during welding was precluded.

Stray Current Corrosion - Aluminum

CORROSION 1975, 1975
This paper covers one phase of a systematic study of the effects of stray current on engineering materials conducted at the Naval Research Laboratory over the past two years. Parameters that might be used in detection of stray current have also been studied.

Stray Current Corrosion-Steel

CORROSION 1974, 1974
Several incidences of severe corrosion on naval ship hulls have occurred recently. The possibility of the corrosion being caused by improper grounding during welding has been eliminated in at least some of these cases. However, the source of the currents in many instances has not been established. Field studies have been made in which the recorded hull

Computers in Stray Current Corrosion Control

CORROSION 1986, 1986
Abstract The random nature of stray currents leaking from d.c. electric tractions in urban agglomerations imposes that the changes in polarization of underground metallic structures, and in any other measurable electric quantity, connected with the stray current flow must be treated as stochastic processes.
