Advanced Engineering Materials, EarlyView.A combined finite element and phase‐field approach predicts the evolution of microstructure during the directional solidification of Ni‐based superalloys. The model reveals how withdrawal rate, temperature gradient, and wall thickness control the dendrite spacing, highlighting the strong effect of surface regions in thin sections where dendrite growth ...

Effect of Alloying and Impurity Elements In Magnesium Alloy Cast Anodes
Corrosion, 1954 Data from extensive laboratory anode efficiency tests and supporting field tests illustrate the need for low impurity levels in the 6% Al—3% Zn magnesium alloy cast anodes. Data are presented which show the detrimental effects of the impurities copper, nickel, iron, lead and tin; the beneficial effect of manganese in counteracting to some extent the ...

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.
