Normal phase of scandium
WebScandium – Thermal Conductivity. Thermal conductivity of Scandium is 15.8 W/ (m·K). The heat transfer characteristics of a solid material are measured by a property called the thermal conductivity, k (or λ), measured in W/m.K. It is a measure of a substance’s ability to transfer heat through a material by conduction. WebThey showed that the melting point of Mg is raised to yo6 and that the maximum solid solubility of Sc in Mg is about 16 at.%. In the present study the Sc-Mg system was studied from o to 60 at. % Sc (c-73.5 wt.% Sc) by thermal, metallographic and X-rays methods. Although the complete Sc-Mg phase diagram was not determined in the present work, it ...
