Impact of MgO Additions on the Oxidation Resistance and Compression Behavior of Vanadium Alloys

open access: yesAdvanced Engineering Materials, EarlyView.
An increase in oxidation resistance at 600 °C is achieved for alloys containing more than 2.5 wt.% MgO. It has been established that, along with V2O5, MgO6V2, and Mg2O7V2 are formed, which are presumed to enhance oxidative stability. Furthermore, the possible transformation of Mg‐vanadates through reaction with CO2, which presumably occurs in this ...

Optimizing thermoelectric generator performance in blast furnace slag Runners: Impact of cooling water flow velocity and enhanced heat transfer

open access: yesCase Studies in Thermal Engineering
Blast Furnace (BF) slag contains substantial thermal energy, yet significant heat is lost as it flows through the Blast Furnace Slag Runner (BFSR), reducing slag fluidity and resulting in considerable energy waste.

Distinct Microstructural Characteristic Lengths Defining Notch Fatigue Crack Initiation and Propagation, and Defect Tolerance in Advanced Steels

open access: yesAdvanced Engineering Materials, EarlyView.
Schematic representation of modes of microcrack nucleation, growth and temporary arrestment at different boundaries, with the criteria for crack propagation in three scenarios: (1) large notch, (2) defect/small sharp notch, and (3) long crack. This work revisits and integrates results on the fatigue behavior of advanced bainitic steels (in particular ...

Integration of OpenCV‐Based Microscopic Adhesive Volume Measurement Into a Pyiron Workflow for Automated Data Analysis

open access: yesAdvanced Engineering Materials, EarlyView.
Residual adhesive after electrode loading in adhesive‐assisted resistance spot welding is quantified through a traceable experimental‐to‐digital workflow. Chromatic confocal topography provides calibrated surface‐height data, while OpenCV detects the electrode imprint and integrates adhesive height into comparable volume metrics.

Reactivity of Carbon Based Materials for Powder Metallurgy Parts and Hard Metal Powders Manufacturing

open access: yesJournal of the Japan Society of Powder and Powder Metallurgy, 2016
Carbon is a key element for powder metallurgy. For example, carbon is the basic alloying element in PM sintered steel, and carbon powders are used as a carbon source for the production of hard metals. However, there are only a few studies about the mechanisms of carbon dissolution and reactivity in dependence on the carbon sources with solid metals ...

Microstructure Modification of Additively Manufactured Mo–9Si–8B by Annealing and Its Effects on High‐Temperature Mechanical Properties

open access: yesAdvanced Engineering Materials, EarlyView.
Postbuild annealing systematically modifies the phase fractions and morphology of EB‐PBF processed Mo–9Si–8B. Quantitative microstructure–property correlations reveal how controlled phase evolution enhances high‐temperature compressive strength and creep resistance.

Dislocation-twin-precipitate synergy imparts 2.3 GPa yield strength and 18.2% ductility in MPEA at 77 K

open access: yesMaterials Research Letters
Achieving an exceptional strength-ductility synergy is essential for cryogenic structural materials. However, ultrahigh-strength alloys frequently suffer from limited ductility, which restricts ductility.

Entropy‐Driven Design of Low‐Melting‐Point Alloys via Compositionally Complex Strategy

open access: yesAdvanced Engineering Materials, EarlyView.
Conventional low‐melting‐point alloys (LMPAs) are limited by a narrow compositional space and inherent property trade‐offs. This review presents an entropy‐driven design strategy that overcomes these limitations, ushering in a new class of low‐melting‐point compositionally complex alloys (LMCCAs).

Twinning-assisted gradient nanocrystallization enabling substantially improved corrosion resistance stainless steels susceptible to sensitization

open access: yesCorrosion Communications
Corrosion is a leading cause of catastrophic safety and environmental accidents in harsh service environments, particularly for stainless steels prone to sensitization. This study demonstrates that cryogenic ultrasonic surface rolling (CUSR) can markedly
