A Knowledge‐Based Approach for Understanding and Managing Additive Manufacturing Data

Advanced Engineering Materials, EarlyView.
Additive manufacturing processes generate a large amount of data. Effectively managing, understanding, and retrieving information from this data remains a major challenge. Therefore, we propose an ontology‐based approach to integrate heterogeneous data, enable semantic queries, and support decision‐making.

Microstructure and enhanced dielectric properties of BaTiO(3)–SiO(2) nanocomposites using hydrogen treated nanoparticles

IET Nanodielectrics, 2019
BaTiO(3) (BT) nanoparticles treated in H(2) and then coated with a layer of SiO(2) were used as the starting material to synthesise BT–SiO(2) nanocomposites through the conventional ceramic process.

Impact of Sustainable Binders Based on Lignin and Collagen on the Volume Stability and Mechanical Properties of MgO‐C Refractories with MgO‐C Recyclates

Advanced Engineering Materials, EarlyView.
Collagen hydrolysate is evaluated as a sustainable binder for MgO‐C refractories. Its thermally induced cross‐linking and gas release lead to expansion and cracking in large bricks, but tailored batches with lignin, recyclates, or fine graphite improve the gas release while thermal treatment and stability.

Effect of sintering process on microstructure and mechanical properties of W–Re alloys

Fenmo yejin jishu
The W–5.0Re–0.5HfC alloys were prepared by powder metallurgy, and the effects of three sintering processes on the microstructure and room-temperature mechanical properties of the alloys were systematically investigated, including hydrogen, vacuum, and ...

Dielectric Barrier Discharge Plasma Deoxidation of Natively Oxide Layer of Copper Powders in a Fluidized Bed

Advanced Engineering Materials, EarlyView.
This paper presents a novel approach to reducing oxide layers on metal powders using low‐temperature hydrogen dielectric barrier discharge plasmas at atmospheric pressure. Unlike conventional hydrogen‐plasma reductions, the powders do not contact the plasma directly.

Development of Sustainable MgO–C Refractories Using MgO–C Recyclates and a Novel Eco‐Friendly Fructose–Tannin Binder Crosslinked With Citric Acid

Advanced Engineering Materials, EarlyView.
This study develops sustainable MgO–C refractories using recycled materials and eco‐friendly fructose–tannin binders. The enhanced performance of citric acid as a cross‐linker and functional additives on mechanical and thermomechanical properties was examined. Characterization included strength tests, immersion trials, and microstructural and inclusion

High temperature annealing of micrometric Zn2SiO4:Mn phosphor powders in fluidized bed [PDF]

, 2008
Micrometric Zn1.8Mn0.2SiO4 phosphor powders prepared by spray pyrolysis have been annealed between 900 and 1200°C under ambient air atmosphere to exalt their luminescence properties. Two original gas-solid fluidization processes have been tested in order
