Activities of Bismuth and Antimony in Liquid Copper Base Alloys by Vapor Pressure Measurements

High-thermoelectric performance of nanostructured bismuth antimony telluride bulk alloys.

The dimensionless thermoelectric figure of merit (ZT) in bismuth antimony telluride (BiSbTe) bulk alloys has remained around 1 for more than 50 years. We show that a peak ZT of 1.4 at 100 degrees C can be achieved in a p-type nanocrystalline BiSbTe bulk alloy. These nanocrystalline bulk materials were made by hot pressing nanopowders that were ball-milled from crystalline ingots under inert con...

Pressure Dependence of Liquid Vapor Pressure: An Improved Gibbs Prediction

A new model for the vapor phase of a pressurized liquid called "the cluster model: which is originally introduced in this work, along with an accurate equation of state for the liquid phase called the LIR, is used to derive an accurate equation for the vapor pressure of liquid as a function of external pressure. The chemical Potential of both phase have been found to be in good agreement wi...

Control Of C/Ti Ratio in Titanium Carbide - Copper Master Alloys Produced by SHS Reactions and its Effect on the Carbide Dispersion In Liquid Copper

Titanium carbide is used as an attractive reinforcement to produce particulate metal matrix composites. One of the problems to use this carbide as a reinforcement in copper-based composites is the lack of wetability in Cu-TiC system. This property improves as the C/Ti ratio in carbide decreases. Problems to use this carbide as a reinforcement in copper-based composites is the lack of wetabiity...
