Composites of aluminum alloy and magnesium alloy with

2019-2-1 · High thermal conductivity, low thermal expansion and low density are three important features in novel materials for high performance electronics, mobile appliions and aerospace. Spark plasma sintering was used to produce light metal–graphite composites with an excellent coination of …

High thermal conductivity of spark plasma sintered …

High‐resolution transmission electron microscopy revealed two different SiC‐SiC boundaries, that is, amorphous and clean boundaries, in addition to a fully crystallized junction phase. A high thermal conductivity was attributed to a low lattice oxygen content and the presence of clean SiC‐SiC boundaries.

High Thermal Conductivity Materials | MRS Bulletin

2011-1-1 · Every university student becomes familiar with the concept of thermal conductivity, a fundamental physical property of materials, through his or her textbooks. Initial work on high thermal conductivity was carried out in 1911 by Eucken, who discovered that diamond was a reasonably good conductor for heat at room temperature.

Thermoelectric properties of spark-plasma sintered

Spark plasma sintering was used as consolidation method to maintain the particle size. The thermoelectric performance of FeSb 2 is limited by its high thermal conductivity. In this work, the thermal conductivity was suppressed by nearly 80% compared to the bulk value by introducing grain boundary stering of phonons on the nanoscale.
