11. Acetylation of Solid Wood. Wood Properties and Process Development
Sammanfattning : The influence of acetylation on selected wood properties has been determined for Scandinavian pine and spruce wood, in order to predict the behavior of acetylated wood when it is used in different applications. Only minor differences in both bending strength and the modulus of elasticity were obtained for acetylated wood when compared with unmodified wood, and can, for practical applications, be considered unaltered.

12. Synthesis and Characterization of Transition Metal Diborides
Sammanfattning : This thesis is devoted towards physical vapor deposition (PVD) of thin films of transition-metal (TM) diborides, focused on the material system TiBx, Ti1-xAlxB2-y and CrBx. The metal diborides are a large family of compounds with both metallic and ceramic properties, due to its bonding nature being a mix of covalent and ionic bonds. LÄS MER
13. Machinability variations in alloy 718 turbine components
Sammanfattning : Machinability Variations in Alloy 718 Turbine Components PAJAZIT AVDOVIC Department of Materials and Manufacturing TechnologyChalmers University of Technology AbstractAlloy 718 has a reputation for being very troublesome during the cutting process. It was suspected that this material was too hard and having too fine grain size and that these characteristics caused damage to cutting tools during processing. LÄS MER
