1. 1. Method to assess machinability of engineering steels using coated carbide tools

   Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Tillämpad materialvetenskap

   Författare :Petra Hedberg; [2021]
   Nyckelord :Machinability; tool wear; coated carbide; non-metallic inclusions; Ca-treated; steel; 42CrMo4;

   Sammanfattning : In this master thesis, performed at Ovako Group R&D (Hofors) a new machining test method for ranking heats of calcium-treated steels, M-Steels, has been proposed.  A total of six different heats of 42CrMo4-M steel in the quenched-and-tempered (Q+T) condition were tested.

3. 2. Evaluation of deformed MnS in different industrial steels by using electrolytic extraction

   Master-uppsats, KTH/Materialvetenskap

   Författare :Shuo Guo; [2017]
   Nyckelord :Non-metallic inclusions; Electrolytic Extraction; Scanning Electron Microscope; Inclusion characterisation; Steel;

   Sammanfattning : The inclusions have a different chemical composition and give the steel different mechanical properties. These inclusions affect several properties of steel. In order to understand how the inclusions will affect the steel properties, the electrolytic extraction of 3D investigate method is applied on the steel grade of 42CrMo4. LÄS MER

4. 3. Three-dimensional Investigations of Different Sulfides in Steels by Using Electrolytic Extraction

   Master-uppsats, KTH/Materialvetenskap

   Författare :Pang Kit Jerry Lam; [2016]
   Nyckelord :Electrolytic extraction EE ; Manganese sulfides MnS ; Heat treatment HT ; Size; Number density per unit volume Nv ; Morphology; Aspect ratio AR ; Particle size distribution PSD ;

   Sammanfattning : The emphasis of this study is focusing on three-dimensional (3D) investigations of the manganese sulfide (MnS) inclusions characteristics in steels by using electrolytic extraction (EE). Two steel grades, 42CrMo4 and 157C, heat treated (HT) at 900 oC were investigated. LÄS MER
