Grain growth stagnation in fully dense nanocrystalline Y2O3 by spark plasma sintering. [PDF]

, 2010
Nanocrystalline (nc) Y2O3 powders with 18nmcrystallite size were sintered using spark plasma sintering (SPS) at 1100 ◦C and 100MPa for different durations. Specimens with 98% density and 106±33nm mean grain size were formed after 20 min.

High‐Entropy Alloy Interlayers Toward Advanced Joining for High‐Performance Structural Applications: Current Progress and Emerging Challenges

Advanced Engineering Materials, EarlyView.
HEA interlayers offer a versatile route for joining high‐performance structural materials. Their compositional and structural design regulates interfacial reactions, suppresses brittle IMCs, and improves metallurgical bonding. Sandwich interlayers further integrate defect healing with precipitation strengthening, enabling improved strength–ductility ...

Materials‐Driven Additive Manufacturing for Electrical Machines: Qualification‐Oriented Design Beyond Geometric Freedom

Advanced Engineering Materials, EarlyView.
This perspective reframes additive manufacturing for electrical machines as a qualification‐limited materials and architecture design problem. It links process–structure–property–performance relationships to magnetic, conducting, dielectric, and thermal property windows, highlighting where AM can enable segmented magnetic circuits, permanent magnet ...

Transparent Alumina/Ceria Nanocomposites By Spark Plasma Sintering [PDF]

Advanced Engineering Materials, 2010
AbstractThe influence of oxides (such as MgO, TiO2, CaO, etc.) on the transparency of polycrystalline alumina compacts are widely studied in the literature. In this work, a completely different approach is developed, consisting of precipitating 0.5 wt.‐% CeO2 nanoparticles (< 5 nm) on the surface of the starting alumina nanopowder (d50 approximately
