Fretting Wear and Corrosion Behavior of the Fe‐35Mn Biodegradable Alloy for Biomedical Applications

Materials and Corrosion, EarlyView.
This study evaluates the corrosion and tribological wear behavior of the Fe‐35Mn alloy, demonstrating superior mechanical stability and a more favorable degradation rate than pure iron, thereby highlighting its potential for biomedical applications. ABSTRACT The biodegradable Fe‐35Mn alloy has emerged as a promising material for temporary implants due ...

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

Materials 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.

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.

Corrosion Analysis of Rapidly Solidified and Subsequently Aged Al‐Ni and Al‐Fe‐Ni Alloys

Materials and Corrosion, EarlyView.
Fe addition modifies intermetallic phase chemistry and microgalvanic interactions in Al‐Ni alloys, shifting corrosion from generalized dissolution to localized attack. ABSTRACT This study investigates the influence of Fe addition and heat treatment on the corrosion behavior of Al–5 wt.%Ni and Al–2 wt.%Fe–1.5 wt.%Ni alloys, with particular emphasis on ...

Controlling the Dynamic Conversion Process of the Water Molecules on the Electrolyte Interface for Producing Free Water

National Materials, EarlyView.
GDY has the capability to reorganize the interfacial H2O structure on the MnOx surface, enabling the rapid evolution of free‐H2O and protons within the electrical double layer, thus promoting the performance of MnOx toward acidic water oxidation.

Suboptimal Model Predictive Control With a Computation Governor: Stability, Recursive Feasibility, and Applications to Alternating Direction Method of Multipliers

Optimal Control Applications and Methods, EarlyView.
Computational governor is shown which simultaneously adjusts the reference and adjusts the constraints. ABSTRACT The paper considers a computational governor strategy to facilitate the implementation of Model Predictive Control (MPC) based on inexact optimization when the time available to compute the solution may be insufficient.
