3. 2. 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

4. 3. Microstructure and wear mechanisms of textured CVD alumina and titanium carbonitride coatings

   Författare :Siamak Shoja; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Plastic deformation; Texture; TKD; Electron microscopy; Coatings; CVD; TiCN; α-alumina; Wear mechanisms;

   Sammanfattning : The aim of this thesis is to find the reasons behind how the wear performance of hard coatings produced by chemical vapor deposition (CVD) is influenced by their texture, as this is today not fully known. Therefore, differently textured coatings were synthesized, and subsequently analyzed both before and after specially designed machining tests. LÄS MER

5. 4. Translational studies on acute myeloid leukemia focus on the receptor tyrosine kinase FLT3

   Författare :Alissa Marhäll; Avdelningen för translationell cancerforskning; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cancer; AML; FLT3;

   Sammanfattning : Among adults, acute myeloid leukemia (AML) is the second most frequent type of leukemia. In spite of recent improvements in the treatment of this disease, a majority of patients develop drug resistance, leading to poor overall survival. One of the factors behind this is mutations in the tyrosine kinase receptor (FLT3). LÄS MER

7. 5. Novel Insights into the Oxidation of High Temperature Alloys - The Role of Environment, Microstructure and Reactive elements

   Författare :Nooshin Mortazavi Seyedeh; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; reactive elements; nitridation; High temperature materials; nitrides; alumina; hydrides; microstructure; chromia; oxidation;

   Sammanfattning : The properties of materials can be deteriorated, when they react with an environment at high temperature and form various types of corrosion products, such as oxides and nitrides. In order to perform successfully at elevated temperatures, all these materials are required to be protected by a slow-growing, continuous and adherent surface oxide layer. LÄS MER
