6. A Method for Dispersive Split Hopkinson Pressure Bar Analysis Applied to High Strain Rate Testing of Spruce Wood
Sammanfattning : En metod för dispersiv analys av försök med delad hopkinsonstång tillämpad på provning av granved vid hög töjningshastighetSyftet var att etablera en metod för att studera sambandet mellan spänning och töjning för granved vid hög töjningshastighet. Detta åstadkoms genom att anpassa och något vidareutveckla tekniken med delad hopkinsonstång ("Split Hopkinson Pressure Bar", SHPB). LÄS MER
7. Diffusion bonding of structural ceramics to superalloys by HIP
Sammanfattning : Diffusion bonding of structural ceramics to superalloys has been investigated. Emphasis was placed on methods resulting in joints durable at elevated temperatures (500 - 700ºC) between these two classes of high - temperature materials. LÄS MER
8. Ti3SiC2 synthesis from TiC and Si powders
Sammanfattning : The aim of this work was to produce Ti3SiC2 from TiC and Si powders and to investigate process parameters with respect to optimised Ti3SiC2 yield. The reaction pathway of Ti3SiC2 formation and the thermochemical degradation reactions were examined. LÄS MER
9. On Surface Characteristics and Microstructural Development of Soft Magnetic Composite Powder and Components
Sammanfattning : Soft Magnetic Composite (SMC) products manufactured by traditional Powder Metallurgical (PM) techniques, are strong candidate materials for electromagnetic applications. Their advantages are based on cost and energy efficient production methods, shape complexity realization and uniquely uniform and isotropic three dimensional (3D) magnetic properties. LÄS MER
10. Sustainable Surface Functionalization of Lightweight Materials : Cerium Oxide Nanoparticles Replacing Chromium in Anodic Coatings and Carbon Nanomaterials for Lightning Strike Protection
Sammanfattning : Aviation accounts for 2-3% of the carbon dioxide emitted globally. One way to reduce emissions is to develop and introduce sustainable, functional, lightweight materials and coatings that increase the lifetime and fuel efficiency of aircraft. LÄS MER
