2. 1. Analysis of thermal shock in brittle materials

   Author : Marianne Collin; KTH; []
   Keywords : thermal shock; thermal stress; stress intensity; vickers indentation; alumina; silicon varbide whisker reinforced alumina;

   Abstract : This thesis concerns thermal shock damage of ceramicmaterials. More specifically the work is focused on theoreticaland practical aspects of a new technique for determining thethermal shock resistance of brittle materials. READ MORE

4. 2. Characterization of nano-scale materials for interconnect and thermal dissipation application in electronics packaging

   Author : Xin Luo; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; thermal conductivity; thermal interface material; thermal management; boron nitride fiber; electrospun nanofiber; lead-free solder; carbon fiber; nano-scale oxide layer; metal matrix composite;

   Abstract : This thesis focuses on studies of nano-scale materials in electronic packaging applications with respect to following aspects: surface analysis of nano-scale oxide of lead-free solder particles, and thermal performance and mechanical property studies of nano-scale fiber and metal composite-based thermal interface materials. The composition and thickness of the solder oxide have a direct impact on the quality of interconnects and the reliability of a packaged system. READ MORE

5. 3. Thermal response test : method development and evaluation

   Author : Signhild Gehlin; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Vattenteknik; Water Resources Engineering;

   Abstract : Since the first introduction of thermal response tests with mobile measurement devices in Sweden and USA in 1995, the method has developed and spread in North America and Europe. Thermal response tests have so far been used primarily for in situ determination of design data for BHE (borehole heat exchanger) systems, but also for evaluation of grout material, heat exchanger types and groundwater effects.

6. 4. Thermal Barrier Coatings : Durability Assessment and Life Prediction

   Author : Robert Eriksson; Sten Johansson; Michael Schütze; Linköpings universitet; []
   Keywords : ;

   Abstract : Thermal barrier coating (TBC) systems are coating systems containing a metallic bond coat and a ceramic top coat. TBCs are used in gas turbines for thermal insulation and oxidation resistance. READ MORE

7. 5. Thermal Barrier Coatings : Failure Mechanisms and Life Prediction

   Author : Krishna Praveen Jonnalagadda; Ru Lin Peng; Xin-Hai Li; Robert Eriksson; Nicholls John; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : Thermal barrier coatings (TBCs) use in the hot sections of gas turbine engine enables them to run at higher temperatures, and as a consequence, achieve higher thermal efficiency. For full operational exploitation of TBCs, understanding their failure and knowing the service life is essential. READ MORE
