2. Effects on Machinability due to Microstructure Variations in Case Hardening Steel
Abstract : Typical products made of case hardening steel are transmission parts like gear wheels, pinions and crown wheels. Case hardening produces a carbon-rich surface and provides the parts with both enhanced hardness and fatigue life. READ MORE

4. Evaluation of Non-Metallic Inclusions after Deformation and Their Effect on the Machinability of Steel
Abstract : 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). READ MORE

5. Evaluations of Non-metallic Inclusionsin Ca-treated Steels and Their Effect on the Machinability
Abstract : 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.
