1. In-situ phase studies of the Zr-H system
Sammanfattning : Zirconium alloys are widely used in the nuclear industry because of their high strength, good corrosion resistance and low neutron absorption cross-section. However, zirconium has strong affinity for hydrogen, which may lead to hydrogen concentration build-up over time during a corrosion reaction when exposed to water. LÄS MER
2. Phase transformation and stability studies of the Zr-H system
Sammanfattning : Zirconium alloys are widely used in the nuclear industry because of their high strength, good corrosion resistance and low neutron absorption cross-section. Zirconium has a strong affinity for hydrogen, however, and if hydrogen concentration builds up, the material will gradually degrade. LÄS MER
3. In-situ TEM Probing of Nanomaterials
Sammanfattning : Nanomaterials because of their small size, may have special properties unlikely to be seen in ordinary types of materials. Nanomaterials like nanotubes,nanowires and nanoparticles are best studied at the nanoscale, vital but also problematic. LÄS MER
4. Running-in of gears - surface and efficiency transformation
Sammanfattning : With ever shorter development times and market demands on overall system performance such as efficiency, reliability and low maintenance, accurate predictive tools are necessary and gear drives prove to be no exception. All these characteristics have an impact on a process which has remained a riddle: running-in. LÄS MER
5. Investigation of Surface Formation in As-Cast and Homogenized 6xxx Aluminium Billets
Sammanfattning : The direct chill (DC) casting technique to produce billets for extrusion and ingots for rollingwas developed in the 1930s. The principle, which is still valid, is a two-stage cooling with a primary cooling at a mould surface followed by water spraying directly on the surface. LÄS MER
