2. 1. Oxidation kinetics of nickel particles

   Author : Richard Karmhag; Uppsala universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Oxidation; kinetics; nickel; particles; UFP; solar absorber; Materialvetenskap; Materials science; Teknisk materialvetenskap; Solid State Physics; fasta tillståndets fysik;

   Abstract : Nanoparticles have an immense surface to volume ratio. This is a key factor to the new properties of some materials made up of such particles. The oxide layer formed on all materials will have a large influence on the behaviour of these materials. The layer isadvantageous in some cases but causes problems in other. READ MORE

4. 2. On high temperature oxidation resistance : Towards the materials genome of high temperature alloys

   Author : Samuel Hallström; John Ågren; Roger Reed; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials Science and Engineering; Teknisk materialvetenskap;

   Abstract : The efficiency of a heat engine increases with increasing service temperature. This leads to a demand for material that can withstand aggressive environments and sometimes also high load at higher and higher temperature. That is the rationale for the work of this thesis. READ MORE

5. 3. Performance of High-temperature Coatings : Oxidation and Interdiffusion

   Author : Xiaoyu Sun; Ru Lin Peng; Johan Moverare; Xin-Hai Li; Lindwall Greta; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; coating; diffusion; phase transformation; oxidation;

   Abstract : The use of aluminiferous coatings profoundly improves the service life of superalloys but leads to the microstructural degradation of superalloys and thus the loss of mechanical properties. To solve this trade-off, two strategies were employed in this research. READ MORE

6. 4. High Temperature Corrosion of FeCrAl Alloys: The influence of water vapour and alkali salt

   Author : Niklas Israelsson; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; pre-oxidation; FeCrAl; kinetics; high temperature corrosion; KCl; water vapour; alumina; oxidation;

   Abstract : The corrosive environment in biomass- and waste-fired boilers has been known for several years. The traditionally used FeCr and FeNiCr steels show limited performance in the aggressive environment that contains more H2O and alkali salts than traditional fuel. READ MORE

7. 5. Microstructure and properties of ceramic matrix composites

   Author : Håkan A. Swan; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; creep resistance; microcracking; oxidation; fracture behaviour; temperature; deformation mechanisms; whisker reinforced CMC materials; electron microscopy;
