1. 1. Characterisation of Non-metallic Inclusions in Special Steels using Electrolytic Extraction

   University essay from KTH/Materialvetenskap

   Author : Josefin Mvele Svensson; [2024]
   Keywords : Non-metallic inclusions; electrolytic extraction; SEM; Icke-metalliska inneslutningar; elektrolytisk extraktion; SEM;

   Abstract : 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.

3. 2. Oligosaccharide Analysis - Assessment of the DNS Method and Specification of Glucans Processed with CGTase

   University essay from Lunds universitet/Bioteknik; Lunds universitet/Bioteknik (master)

   Author : Matilda Johansson; [2022]
   Keywords : CGTase; DNS; Chromatography; HPAEC; HPAE; Carbohydrate; Carbohydrates; Glucans; Cyclodextrin glycosyltransferase; Biotechnology; Bioteknik; Flory; Enza; Enzyme; Technology and Engineering;

   Abstract : In this study, the reagent 3,5-dinitrosalicylic acid (DNS) and high-performance anion exchange chromatography (HPAEC) were used for carbohydrate characterisation. It was revealed that the DNS reaction is not exclusive to reducing ends as commonly thought, but rather that the reagent reacts with other parts of the carbohydrate molecules as well. READ MORE

4. 3. Characterisation of additively manufactured Inconel 718 alloy by using electrolytic extraction

   University essay from KTH/Materialvetenskap

   Author : Leyla Koort; Viktoria Sutorius Trollbäck; [2021]
   Keywords : ;

   Abstract : 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).

5. 4. Evaluation of deformed MnS in different industrial steels by using electrolytic extraction

   University essay from KTH/Materialvetenskap

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

   Abstract : 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. READ MORE
