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. Investigations of Large Size Non-Metallic Inclusions in the Nickel-based alloy Inconel 718
University essay from KTH/MaterialvetenskapAbstract : Inclusions of different types are present in all steels. How dangerous these are for the properties of the material depends on their chemical composition and the manufacturing process. READ MORE

3. Characterisation of additively manufactured Inconel 718 alloy by using electrolytic extraction
University essay from KTH/MaterialvetenskapAbstract : The formation of non-metallic inclusions (NMIs) are common in all steel grades and it is not possible as of today to be able to remove all of them. The inclusions are categorised into endogenous (oxides, nitrides, sulfides, carbides, and phosphides), and exogenous (entrapment of nonmetals: slag, mold). READ MORE

4. Evaluation of different non-metallic inclusions in steel chips by using electrolytic extraction : Evaluation of a methodology for electrolytic extraction and scanning electron microscopy - energy dispersive spectroscopy (SEM-EDS) analysis
University essay from KTH/MaterialvetenskapAbstract : Analysing non-metallic inclusions (NMI) by conventional microscopy is prone to errors. Better imaging can be achieved by using electrolytic extraction (EE) to effectively dissolve the metal matrix, freeing the inclusions so that they can be collected on a filter. READ MORE

5. Evaluation of the Effect of Non-Metallic Inclusions on the Corrosion Resistance of Stainless Steels and Nickel-based Alloys
University essay from KTH/MaterialvetenskapAbstract : Non-metallic inclusions (NMI) are small impurities that can always be found in steel and other materials. NMIs are of great importance because they may negatively impact various properties of the steel, depending on their composition, morphology and numbers. READ MORE
