Combined Process‐ and Phase‐Field‐Simulation to Predict the Microstructure of Single‐Crystal Ni‐Based Superalloys

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 ...

The Influence of Substrate, Binder, and Additives on Suspension Coating Properties at Elevated Temperatures

Sci
A study of the antifriction properties of suspension solid-lubricating coatings based on molybdenum disulfide (MoS2) at high temperatures depending on the type of substrate, binder, additives, and load parameters was carried out.

Characterization of a Recyclate‐Based MgO‐Steel Composite As‐Sintered Inert Anode Candidate After Exposure to Cryolite Electrolysis

Advanced Engineering Materials, EarlyView.
Carbon‐free inert anodes are essential for decarbonizing aluminum electrolysis. This study investigates a recyclate‐based MgO‐316L steel composite anode tested under galvanostatic Hall–Héroult conditions in cryolite at 1000°C. Microstructural analysis reveals selective MgO fluorination, spinel and oxide layer formation, electrolyte infiltration, and ...

Design and Mechanical Properties of ZTA–Niobium Composites with Reduced Graphene Oxide

Ceramics
Niobium–graphene oxide–zirconia-toughened alumina (ZTA) composites were produced by wet mixing and spark plasma sintering. The microstructure and mechanical properties of this novel composite have been studied. The results show that niobium particles are

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.

Low-Temperature Rapid Synthesis and Superconductivity of Fe-Based Oxypnictide Superconductors

, 2010
we were able to develop a novel method to synthesize Fe-based oxypnictide superconductors. By using LnAs and FeO as the starting materials and a ball-milling process prior to solid-state sintering, Tc as high as 50.7 K was obtained with the sample of Sm ...
