1. 11. Microstructure and plastic deformation of textured CVD alumina coatings

   Författare :Siamak Shoja; Chalmers tekniska högskola; []
   Nyckelord :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; α-Al2O3; Texture; Coatings; TKD; Plastic deformation; Deformation mechanisms; Electron microscopy; CVD;

   Sammanfattning : It is known that the wear performance of α-alumina coatings produced by chemical vapor deposition (CVD) is significantly influenced by the type and degree of texture. However, the main reasons behind this behavior are not fully understood. This thesis contains studies of two related topics for increasing the understanding of α-alumina coatings. LÄS MER

3. 12. Thermal Stability of Electrodeposited Nanocrystalline Ni- and Co-Based Materials

   Författare :Melina da Silva; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; nanocrystalline materials; 3DAP; nanocomposite; thermal stability; TEM; nickel; texture; DSC; cobalt; grain growth; EBSD;

   Sammanfattning : The attractive properties associated with nanocrystalline materials are to a large extent a result of their high intercrystalline volume fraction. However, the intrinsic instability of the nanostructured state may compromise the gain in properties by the occurrence of grain growth during exposure at elevated temperatures. LÄS MER

4. 13. Structure design for perception of sweetness in food gels

   Författare :Karin Holm; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; diffusion; pectin; texture; gelatin; gels; sensory analysis; rheology; sweetness;

   Sammanfattning : The production of foods with reduced sugar contents is desired and asked for. However, when reducing the sugar concentration, sweetness and structure and texture properties are altered. There is thus a need for a deeper understanding of the complex relations between a food’s structure, texture and taste. LÄS MER

5. 14. Microstructure and hydrogen embrittlement of additively manufactured Ti-6Al-4V

   Författare :Magnus Neikter; Marta-Lena Antti; Pia Åkerfeldt; Robert Pederson; Ola Harrysson; Luleå tekniska universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ti-6Al-4V; Additive Manufacturing; Texture; Microstructure; Hydrogen Embrittlement; Materialteknik; Engineering Materials;

   Sammanfattning : The work of this doctoral thesis has been performed between the 24th of August 2015 to the 6th of September 2019. The general purpose of this work has been to increase the knowledge of additively manufactured Ti-6Al-4V when it comes to microstructure, texture and hydrogen embrittlement. LÄS MER

7. 15. Sensory Dynamics in Emulsion Products Differing in Fat Content

   Författare :Karin Wendin; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; microstructure; smell; texture; rheology; flavour; fat content; taste; sensory analysis; time intensity; ordinary differential equation; polynomial; emulsion products;

   Sammanfattning : Flavour, taste and texture are important qualities when purchasing food and the richness and smoothness of fat are desired properties for many individuals. However, fat is the major nutrition concern of many consumers. It is therefore important to be able to produce attractive products containing low amounts of fat. LÄS MER
