Magnetic Flux Guides by Material Extrusion

Advanced Science, EarlyView.
Magnetic flux guidance can increase inductive coupling and forces for magnetic sensors, actuators, and transducers. Here, a magnetic material extrusion method is used to fabricate flux concentration structures of arbitrary shapes with a magnetic permeability of 42. In line with simulation analysis, experimental results show that these materials provide

Achieving Fast Charging and Superior Cycling Stability Single‐Crystal Ni‐Rich Cathodes by Ultrafast Aqueous Washing

Advanced Science, EarlyView.
Prolonged water washing severely damages the surface layered structure of single‐crystal Ni‐rich cathodes, forming a thick rock‐salt barrier. In contrast, our 3‐min ultrafast washing removes residual lithium while confining surface reconstruction to an ultrathin 2–4 nm layer, thereby unlocking excellent fast‐charging and cycling stability.

Spark Plasma Sintering: Process Fundamentals

Spark Plasma Sintering of Materials, 2019
Spark plasma sintering (SPS) is a rapid technique. Its processing parameters are usually low-voltage and low-pressure acting, using a uniaxial force and pulsed direct current (DC) to carry out high efficiency consolidation of the powder. This technique has been widely applied for various materials processing in the recent years. First, a description of

Microwave Sintering Process Model

Journal of Microwave Power and Electromagnetic Energy, 2003
In order to simulate and optimize the microwave sintering of a silicon nitride and tungsten carbide/cobalt toolbits process, a microwave sintering process model has been built. A cylindrical sintering furnace was used containing a heat insulating layer, a susceptor layer, and an alumina tube containing the green toolbit parts between parallel ...

Dislocation Activated Sintering Processes

Powder Metallurgy, 1985
On sphere-plate models made from copper it is shown that during sintering the dislocation density increases considerably in the contact region. Its distribution and time-dependent alteration are able to be analysed by means of the Kessel-technique and described quantitatively. The same effect is observed during sintering compacts of electrolytic copper
