Dual‐Comb Spectroscopy With Fully Controlled Repetition Rate and Offset Frequency of Quantum Cascade Laser Frequency Combs

Laser &Photonics Reviews, EarlyView.
Independent control of the repetition rate and offset frequency is demonstrated in quantum cascade laser frequency combs using radio‐frequency injection and thermal tuning. A revised comb model anchored at optical frequencies captures the unique behavior under radio‐frequency injection and enables precise frequency control.

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

Materials 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

New Insights About the Role of Sn‐Rich and Pb‐Rich Phases Over the Corrosion Mechanism of Low‐Tin Quaternary Bronze Alloys Under Sulfur‐Containing Conditions

Materials and Corrosion, EarlyView.
A mechanistic proposal for the initial steps of quaternary bronze corrosion in media containing sulfate was described. The process is driven by microgalvanic effects along the microstructure, generating anodic sites over lead and tin rich phases and cathodic sites onto Cu‐rich phases.

Acoustic Activity of Intergranular Corrosion Sensitized AISI 304L in Double‐Loop Electrochemical Potentiodynamic Reactivation Test

Materials and Corrosion, EarlyView.
Intergranular corrosion of AISI 304L is analyzed, combining DLEPR test and AE. Slow scan rate polarization reveals time‐shifted and frequency‐dependent acoustic emission in the active region of the DLEPR curve, allowing a separation between passive oxide rupture, intergranular corrosion and pitting. ABSTRACT Intergranular corrosion (IGC) susceptibility

Role of Si Alloying in the Microstructure Evolution and Corrosion Performance of ZnAlMg Coatings

Materials and Corrosion, EarlyView.
Si alloying refines the coating microstructure and enables formation of Mg2Si. When present at the surface, this phase is the strongest early source of Mg2+, providing short‐term protection, followed by dissolution of MgZn2 and Zn and formation of more stable corrosion products.

Investigation of the Effects of Surface and Heat Treatment on the Corrosion Behavior of Additively Manufactured AlSi10Mg

Materials and Corrosion, EarlyView.
Surface finish and heat treatment strongly affect the corrosion behavior of AM AlSi10Mg. Polished samples show the highest corrosion resistance, while as‐built ones suffer from surface roughness and weak oxide layers. Stress relief (SR300) improves the corrosion potential but lowers pitting resistance due to Si network dissolution.
