1. Microstructural changes in high strength steels exposed to large deformation and high strain rates
Sammanfattning : Increasing steel prices and environmental aspects have put forward the demand to reduce material consumption and energy usage in manufacturing industry and near-net-shape manufacturing techniques have thus become increasingly important. High-velocity parting-off,high-velocity forming and cold ring rolling are three such manufacturing methods that exhibit great potentials in terms of material waste reduction. LÄS MER
2. Corrosion of High-Temperature Alloys in Molten Salts
Sammanfattning : Concentrated solar power (CSP) is an interesting technology that involves storing solar energy in the form of heat and subsequently converting it into electricity. The third-generation (Gen3) CSP plants aim to operate at temperatures >700°C, necessitating the deployment of new heat storage materials that can withstand such high operating temperatures. LÄS MER
3. CO studies of Herbig-Haro regions
Sammanfattning : High resolution CO (J=1-0) observations of HH 7-11 in NGC 123? and the region around Lk Ha 224 in NGC 7129, using the 25m Millimeter Wave Telescope at Onsala, Sweden, have resulted in detailed maps. These dark cloud regions, forming stars of low to intermediate mass, show signs of shock excitation, identified as Herbig-Haro objects and H?0 masers. LÄS MER
4. Ni-based coatings for high temperature corrosion protection
Sammanfattning : Biomass/waste-fired boilers severely suffer from high temperature corrosion of critical load-bearing components, e.g. water-wall and superheater tubes, due to presence of Cl-containing corrosive species. LÄS MER
5. Corrosion Behavior of HVAF-Sprayed Bi-Layer Coatings
Sammanfattning : In a variety of engineering applications, components are subjected to corrosive environment. Protective coatings are essential to improve the functional performances and/or extend the lifetime of the components. LÄS MER
