National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

Metallurgy, Thermal Stability, and Failure Mode of the Commercial Bi-Te-Based Thermoelectric Modules.

DE2009957291

Publication Date	2009
Personal Author	Yang, N. Y. C.; Morales, A. M.
Page Count	60
Abstract	BiTebased thermoelectric (TE) alloys are excellent candidates for power generation modules. We are interested in reliable TE modules for long-term use at or below 200DGC. It is known that the metallurgical characteristics of TE materials and of interconnect components affect the performance of TE modules. Thus, we have conducted an extensive scientific investigation of several commercial TE modules to determine whether they meet our technical requirements. Our main focus is on the metallurgy and thermal stability of (Bi,Sb)2(Te,Se)3 TE compounds and of other materials used in TE modules in the temperature range between 25DGC and 200DGC.
