Spheroidization of Alumina Powders for Additive Manufacturing Applications by DC Plasma Technology [PDF]

Molecules
Alumina is the most widely used oxide ceramic, and its applications are widespread in engineering and in biomedical fields. Its spheroidization was performed by a prototypal direct current (DC) thermal plasma, which was designed and installed at ENEA ...

Spheroidal ambisonics: Spatial audio in spheroidal bases [PDF]

JASA Express Letters, 2021
Ambisonics is an established framework to capture and reproduce spatial sound fields based on the spherical harmonics representation [Gerzon (1973). J. Audio Eng. Soc. 21(1), 2–10]. A generalization—spheroidal ambisonics—based on spheroidal wave functions is proposed for use with spheroidal microphone arrays.

A review on the preparation and characterization methods of spherical explosive crystals

Journal of Materials Research and Technology, 2023
Spherical explosive crystals refer to explosives with a spherical morphology. Compared to polyhedral explosive crystals, spherical explosive crystals do not have sharp edges or corners, and have a lower probability of generating hot spots due to the ...

A Cell’s Viscoelasticity Measurement Method Based on the Spheroidization Process of Non-Spherical Shaped Cell

Sensors, 2021
The mechanical properties of biological cells, especially the elastic modulus and viscosity of cells, have been identified to reflect cell viability and cell states. The existing measuring techniques need additional equipment or operation condition. This

Effect of pearlitic and bainitic initial microstructure on cementite spheroidization in rail steels

Journal of Materials Research and Technology, 2023
To improve the performance of the rails and wheels for the railway industry, new microstructures need to be researched. Nevertheless, the soft region observed in the weld heat-affected zone (HAZ), caused by the spheroidization of cementite, leads to ...

Effect of multi-pass deformation on hot flow behavior and microstructure evolution mechanism of Ti–6Al–4V alloy fabricated by hot isostatic pressing

Journal of Materials Research and Technology, 2022
The hot flow behavior, spheroidization, dynamic recrystallization (DRX) and fusing of lamellar ɑ phase for hot isostatic pressed Ti–6Al–4V titanium alloy was investigated at 950°C-900°C–850 °C with the total deformation amount of 70% during multi-pass ...

Towards low-cost sodium-ion batteries: electrode behavior of graphite electrodes obtained from spheroidization waste fractions and their structure-property relations

JPhys Energy, 2022
Electrode materials for lithium-ion batteries (LIBs) typically show spherical particle shapes. For cathode materials, the spherical shape is obtained through the synthesis method.
