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.

Effect of TiO2 on Grain Refining of Amorphous Si3N4 and the Grain-refined Mechanism.
Journal of the Japan Society of Powder and Powder Metallurgy, 1997 Amorphous Si3N4/TiO2 compacted bodies were heated at 1490°C, for 1 to 10 hr under N2 pressures of 0.92 and 1000 atm, and the effect of N2 pressure on the resulting grain refining was investigated, to clarify the role of TiO2 in the grain-refined mechanism.

Low‐Angle Grain Boundaries and Re‐Segregation in Single‐Crystalline Ni‐Base Superalloys
Advanced Engineering Materials, EarlyView.This work demonstrates that Re‐segregation at low‐angle grain boundaries (LAGBs) in Ni‐base superalloys is influenced by misorientation angle. Advanced microscopy and atom probe tomography reveal that higher misorientation angles increases Re‐segregation.

Advanced Engineering Materials, EarlyView.The subject of this work is the development of a corrosion‐protective coating on steel sheets for form hardening. Rapid heating in an extreme high vacuum (XHV)‐adequate atmosphere is a useful method to prevent oxidation during alloying of 22MnB5 and aluminum to obtain a metallurgical bonding.

Advanced Engineering Materials, EarlyView.New features on yttria‐stabilized zirconia after exposure at 1500°C: Newly discovered pyramidal structures on an old material. After exposure at 1550°C on the cross section of YSZ new features, namely pyramidal structures are discovered. These structures grow with time, increase in numbers, appear as singularities, are often arranged in strings, and ...

Discussion on grain refining mechanism of AM30 alloy inoculated by MgCO3
Journal of Magnesium and Alloys, 2017 AM30 was inoculated by MgCO3 powder with different holding time. The influence of MgO decomposed by MgCO3 on the grain refinement effect was mainly discussed in the present study. Three sets of comparative samples were prepared.
