1. Thermal and mechanical behaviour of railway wheel steel
Sammanfattning : The wish to increase loads and speeds of trains puts higher demand on construc¬tion, engineering and material than ever before. Therefore it is necessary to con¬tinuously develop technology to meet these increasing requirements. LÄS MER
2. On the relationship between microstructure, process parameters and mechanical properties of boron steels
Sammanfattning : The continuous development of the press hardening technology has led to stronger, lighter and more environmentally friendly components. Utilising the varying properties of boron steel at different temperatures enables great design freedom, while also attaining high strength in the final component. LÄS MER
3. Microstructure and mechanical properties of a 5 wt.% Cr cold work tool steel : Influence of heat treatment procedure
Sammanfattning : The demand for Advanced High Strength Steel (AHSS) in the automotive industry is increasing day by day. It is mainly motivated by the fact that AHSS can be used as thin sheets while having high strengths. LÄS MER
4. Effect of heat treatment on microstructure and mechanical properties of a 5 wt.% Cr cold work tool steel
Sammanfattning : This work presents investigations related to phase transformations occurring inthe 5 wt.% Cr cold work tool steel Caldie during hardening and tempering treatments. LÄS MER
5. Microstructural manipulation by laser irradiation of prepared samples : The ’Snapshot Method’
Sammanfattning : Various metallurgical microstructures and their formation are studied in this thesis by using a laser beam to melt a variety of materials with different chemical compositions over a range of thermal cycles. The laser beam was used conventionally in a narrow gap multi-layer weld, used for welding large depths with filler wire additions, as well as a non-traditional simulated welding approach labelled here as the Snapshot method.
