1. Characterisation of Non-metallic Inclusions in Special Steels using Electrolytic Extraction
University essay from KTH/MaterialvetenskapAbstract : When producing high strength special steels strict requirements are in place to assure the quality of the final product, both in terms of harmful elements and the content of non-metallic inclusions (NMI). Achieving cleanliness is a gradual process where all the steps of the production process are inter- connected, meaning that it is crucial to know the influence of each step in order to assure the contents of the final product.

2. Image analysis of Light Optical Microscopy (LOM) images of metallurgical samples
University essay from Uppsala universitet/Institutionen för informationsteknologiAbstract : Processing metals in different ways often requires stringent quality control to ensure the quality of the processed metal. This master's thesis aims to develop methods for evaluating the quality of metals via image analysis rather than inspecting images manually as it traditionally has been done. READ MORE

3. Optical Emission Spectroscopy Pulse Distribution Analysis on Steel Production Samples : Accuracy, sample variation, spread in different samples and steel grades/routes
University essay from KTH/MaterialvetenskapAbstract : This thesis work aimed to contribute to the development of online characterization techniques for non-metallic inclusions in steelmaking. The study focused on assessing the precision and accuracy of the optical emission spectroscopy pulse distribution analysis (OES/PDA) technique using asreference light optical microscope (LOM) and scanning electron microscope(SEM).

4. Investigations of Tool Wear Mechanisms in the Turning of Conventional, Calcium Treated and Ultraclean Steels
University essay from KTH/MaterialvetenskapAbstract : Application of clean and ultraclean steels have shown to provide favourable mechanical properties for bearings and transmission components, specifically regarding fatigue performance, compared to conventional steel grades. Clean steels are characterized by containing a very low level of non-metallic inclusions. READ MORE

5. Investigation of non-metallic inclusions and chip properties in Cu-based alloys by numerical analysis
University essay from KTH/MaterialvetenskapAbstract : Analysis of the macrostructure of metallic alloys is of utmost importance as there is a direct correlation on the physical properties and some features of the structures. This is true for copper based alloys and the non-metallic inclusions (NMI) that are enclosed in their structure. READ MORE
