1. Steel characteristics and their link to chip breaking and tool wear in metal cutting
Sammanfattning : The vision of this thesis is to study how it is possible to obtain optimised workpieces during metal cutting processes in industry. Specifically, the work is aimed to increase the understanding between the steel characteristics and their link to the chip breaking and tool wear during metal cutting. LÄS MER
2. Evaluations of Non-metallic Inclusionsin Ca-treated Steels and Their Effect on the Machinability
Sammanfattning : In recent decades, a considerable development of steel with respect to the performance of steel has taken place, which also has resulted in large challenges to process these steel grades. Therefore, it is essential to make suitable modifications of non-metallic inclusions (NMI) in the steelmaking process and to have a good control of its characteristics to meet the target mechanical properties and to obtain a good machinability.

3. Characterization of factors interacting in CGI machining : machinability - material microstructure - material physical properties
Sammanfattning : The Swedish truck industry is forced to find new material solutions to achieve lighter engines with increased strength. Customers and new environmental regulations demand both higher specific power and more environmentally friendly trucks, and this places a rising pressure on the manufactures. LÄS MER
4. Evaluation of Non-Metallic Inclusions after Deformation and Their Effect on the Machinability of Steel
Sammanfattning : The presence of non-metallic inclusions (NMIs) have critical effects on both the mechanical properties and machinability of steels. In the present thesis, one focus is to study the characteristics of deformed sulfides (MnS) for a stainless steel (3R65) and a tool steel (42CrMo4). LÄS MER
