1. A study of the adhesion strength of plasma sprayed coatings
Sammanfattning : .... LÄS MER
2. On Peritectic Reactions and Transformations and Hot Forming of Cast Structures
Sammanfattning : This thesis deals with peritectic reactions and transformations that occur during the solidification of many alloys. Peritectics are believed to be a major cause of crack-formation in many steels, thus, good knowledge of the mechanisms by which these phenomena occur is essential for preventing such defects. LÄS MER
3. The Atmospheric Corrosion of Magnesium Alloys : Influence of Microstructure and Environments
Sammanfattning : The low density and high specific strength of magnesium alloys have created a great deal of interest in the use of these alloys in the automotive and aerospace industries and in portable electronics. All of these industries deal with applications in which weight is extremely important. LÄS MER
4. Aspects on finite element simulation of sheet metal forming processes
Sammanfattning : This thesis has focused on four different aspects of finite element simulation of sheet metal forming processes. Four substantial research areas are the development of a methodology for predicting the limiting strains in connection with the Forming Limit Diagram, the applicable mode of procedure for finite element simulation of the hydromechanical deep drawing process, the adaptive mesh refinement strategy based on gradients of the effective plastic stresses and strains; and the reliability and sensitivity assessments within sheet metal forming processes.

5. Surface and Inner Deformation during Shape Rolling of High Speed Steels
Sammanfattning : Shape rolling is a common manufacturing process used to produce long products i.e. bars and wire. One of the problems that might occur during rolling is defect formation leading to rejection of the finished product. LÄS MER
