Hydrogen‐Enhanced Stress Corrosion Cracking of Wire Arc Additive Manufactured Inconel 625 Superalloy in NaCl Solution: Mechanism of Synergistic Degradation

open access: yesMaterials and Corrosion, EarlyView.
Hydrogen‐enhanced SCC of WAAM Inconel 625 in 3.5 wt.% NaCl solution. Hydrogen charging reduces passive film stability (lower corrosion potential) and promotes pitting at Laves phase/matrix interfaces. Stress corrosion cracks propagate along Laves‐rich regions, leading to quasi‐cleavage brittle fracture.

Hydrogen Analyses of FSW Cu‐OFP Tested Under Creep Conditions in Sulphide Containing Environment

open access: yesMaterials and Corrosion, EarlyView.
Friction stir welded Cu‐OFP exhibits elevated creep rates in sulphide‐containing aqueous environments, with creep increasing as sulphide concentration rises. Hydrogen measurements indicate that sulphide exposure does not increase hydrogen content. ABSTRACT Friction stir welded oxygen‐free phosphorus‐doped copper (FSW Cu‐OFP) is a candidate material for

Corrosion Behavior of Magnesium Alloys in Alkaline Solutions Simulating a Low‐Level Radioactive Waste Repository

open access: yesMaterials and Corrosion, EarlyView.
The corrosion rates of two types of magnesium alloys in an alkaline solution containing crushed ordinary Portland cement paste grains decreased with increasing immersion time. This decrease was attributed to the formation of a protective layer containing brucite and hydrotalcite on the specimen surfaces.

High‐Temperature Corrosion of Unpassivated Carbon Steel in Simulated Boiler Water: Electrochemical Thresholds and Mechanisms for Chloride and Sulphate Contamination

open access: yesMaterials and Corrosion, EarlyView.
Through a combination of in situ electrochemical corrosion rate measurements and FactSage thermochemistry modeling, chloride and sulphate ions were found to influence the corrosion of carbon steel in high‐temperature boiler water through distinct mechanisms: chloride acidifies the solution, raising iron solubility, while sulphate leaves solubility ...

Effect of Heat Treatment on Hydrogen Embrittlement of Electrodeposited Copper

open access: yesMaterials and Corrosion, EarlyView.
This work explores how entrapped hydrogen can cause embrittlement of copper, although this embrittlement is only evidenced during slow strain testing. We demonstrate that significant amounts of hydrogen are trapped in nano‐cavities and investigate the impact of heat treatment in changing the hydrogen distribution and the resulting embrittlement ...
