Protective Effects of Er:YAG Laser and PRG Pro‐Care Gel on Enamel Demineralization

open access: yesLasers in Surgery and Medicine, EarlyView.
ABSTRACT Objectives Bioactive surface pre‐reacted glass‐ionomer (S‐PRG) technology and high‐power laser irradiation have been investigated as promising preventive approaches. S‐PRG particles exhibit multifunctional bioactive glass properties, with the ability to release and recharge ions.

Metallographic Spheroidization Rate Classification by Using Deep Learning

open access: yesEngineering Reports
In the steel manufacturing process, spheroidizing annealing is a crucial heat treatment step primarily aimed at improving the ductility and machinability of the material. Currently, the determination of the spheroidization rate in metals mainly relies on

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.

Development of Calcium‐Based Coatings to Mitigate Vanadate Corrosion

open access: yesMaterials and Corrosion, EarlyView.
Ca‐rich coatings can suppress the corrosive attack of molten V2O5 by forming Ca2 V2 O7 and Ca V2 O6. For this, a large Ca‐reservoir is key to mitigate corrosion at 600°C and 700°C. ABSTRACT Vanadate corrosion occurs in devices powered by heavy fuel oil, such as stationary turbines.

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

open access: yesMaterials 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.

Credibility of various plastometric methods in simulation of hot rolling of the steel round bar

open access: yesMetalurgija, 2014
Rolling of round bar made of steel 32CrB4 was simulated physically. The interrupted torsion test led to the final microstructure with coarser grains, however, thanks to comparatively large dimensions of the sample this type of experiment was not so ...

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

open access: yesMaterials 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.
