Temperature-dependent thermal properties of spark plasma sintered alumina [PDF]

Science of Sintering, 2017
In this work, we report temperature-dependent thermal properties of alumina powder and bulk alumina consolidated by spark plasma sintering method. The properties were measured between room temperature and 250ºC using a thermal constants analyzer.

Vibrations and Heat Transfer in Glasses: The Role Played by Disorder

Comptes Rendus. Physique, 2023
Amorphous materials are also distinguished from crystals by their thermal properties. The structural disorder seems to be responsible both for a significant increase in heat capacity compared to crystals of the same composition, but also for a ...

Manipulation of the thermal conductivity for two-phase WC-Ni composites through a microstructure-based model along with key experiments

Journal of Materials Research and Technology, 2023
Thermal conductivity, one of critical properties for composite materials, constitutes an indispensable part of high-efficient materials design. However, a quantitative model to describe the thermal conductivity of two-phase composites has yet to be ...

Thermal conductivity temperature dependence of water confined in nanoporous silicon

Journal of Physics: Condensed Matter, 2022
Abstract Recently, it has been shown that high density nanoconfined water was the reason of the important enhancement of the effective thermal conductivity up to a factor of 50% of a nanoporous silicon filled with water. In this work, using molecular dynamics simulations, we further investigate the role of the temperature T (from 285 to ...

Stable thermal transport in reduced graphene-oxide aerogel at elevated temperatures

Materials Research Express, 2020
We investigate thermal transport in three-dimensional graphene aerogel networks at elevated temperatures. The aerogels are solution-processed from graphene-oxide flakes using amine-based linkers and then partially reduced to impart stability in the ...

Simulation of nonlinear convective thixotropic liquid with Cattaneo-Christov heat flux

Results in Physics, 2018
In this communication we utilized a modified Fourier approach featuring thermal relaxation effect in nonlinear convective flow by a vertical exponentially stretchable surface. Temperature-dependent thermal conductivity describes the heat transfer process.
