1. Creep modelling of particle strengthened steels
Sammanfattning : Materials used in thermal power plants have to resist creep deformation for time periods up to 30 years. Material evaluation is typically based on creep testing with a maximum duration of a few years. This information is used as input when empirically deriving models for creep. LÄS MER
2. Creep modelling of particle strengthened steels
Sammanfattning : Materials to be used in thermal power plants have to resist creep deformation for time periods up to 30 years. The role of alloying elements for creep strength of 9-12% Cr steels is analysed. The creep strength in these steels relies on minor additions of alloying elements. LÄS MER
3. Technical and contractual aspects in winter highway and railway operation and maintenance : a survey of current technical systems and contract forms in Sweden
Sammanfattning : .... LÄS MER
4. Prognos av vägars bärförmåga vid tjällossningen : användning av temperatur som nyckeltal
Sammanfattning : The global trend towards a warmer climate and temperatures near or just above 0 °C during winter months, will most likely be more common in future. One of the consequences of this climate change could, in a worst-case scenario, be freezing and thawing over a significant part of the winter with corresponding road bearing capacity problems.

5. Road Design for Future Maintenance : Life-cycle Cost Analyses for Road Barriers
Sammanfattning : The cost of a road construction over its service life is a function of design, quality of construction as well as maintenance strategies and operations. An optimal life-cycle cost for a road requires evaluations of the above mentioned components. LÄS MER
