Advanced Engineering Materials, EarlyView.The corrosion performance of AlSi7Mg and AlSi10Mg alloys produced through selective laser melting (SLM) was examined under compressive stress in a chloride environment. Electrochemical analyses, including open‐circuit potential (OCP), potentiodynamic polarization (CPP), and electrochemical impedance spectroscopy (EIS), were complemented by scanning ...

LOW-FREQUENCY SWASH OSCILLATION
Doboku Gakkai Ronbunshu, 1993 Swash oscillation の周期は入射波のそれに比べて長くなることが知られている. こうした swash oscillation の長周期化を水理実験および有限振幅長波理論に基づく数値モデルにより検討し, 長周期波のほかに, swash zone での寄せ波と引き波の時系列に依存する追い付き・合体・吸収といった相互干渉によっても長周期の swash oscillation が形成されることを示した.

Nonergodic Brownian oscillator: low-frequency response
Journal of Statistical Mechanics: Theory and Experiment, 2023 Abstract An undisturbed Brownian oscillator may not reach thermal equilibrium with the thermal bath due to the formation of a localized normal mode. The latter may emerge when the spectrum of the thermal bath has a finite upper bound ω 0 and the oscillator natural frequency exceeds a critical value

Powder Optimization Strategies for Binder Jetting Printing of BaTiO3 and Ba0,6Sr0,4TiO3 Ceramics
Advanced Engineering Materials, EarlyView.Powder optimization is investigated to enable binder jetting of BaTiO3 and Ba0.6Sr0.4TiO3 ferroelectric ceramics. The antagonistic relationship between flowability and binder compatibility is addressed through binder impregnation of granulated powders and fumed silica addition to fine powders.

Advanced Engineering Materials, EarlyView.The wettability of aluminum droplets (Al) on different copper substrates (Cu), where liquid Al spreads on solid Cu surfaces to form a liquid–solid interface, is studied numerically and experimentally. The experimental and numerical results show good agreement in the fast‐spreading regime.
