  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.

The theories of Mutual Aid and International Solidarity are used to construct two opposing “solidarity” and “charity” models of foreign aid, against which the OPC model is compared. READ MORE
