  2. 1. On particles and slags in steel casting

    Author : Dimitrios Siafakas; Anders E.W. Jarfors; Taishi Matsushita; Sridhar Seetharaman; Jönköping University; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hadfield steel; deoxidation; grain size; inoculation; particles; viscosity; slag;

    Abstract : Hadfield steel is widely accepted as one of the most important steel alloys utilized in industrial applications where high impact strength and wear resistance is required. Like in most metallic alloys used for component casting, the mechanical properties of Hadfield steel are directly connected with the microstructure of the material. READ MORE

  5. 3. Inclusions and/or Particles Engineering for Grain Refining Purposes in Ferritic Fe-20mass%Cr alloys

    Author : Jesper Janis; Pär Jönsson; Keiji Nakajima; Lauri Holappa; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Inclusions; Particles; Grain size; High Cr; Ferritic; Grain refining; Solidification; Pinning effect; Stainless steel; Oxides; Nitrides; Metallurgical process engineering; Metallurgisk processteknik;

    Abstract : Compared to more common used austenitic stainless steels, ferritic stainless steels contain very low amounts of the expensive alloying element Ni. In addition, they have good corrosion properties, but are sometimes suffering from poor weldability and bad mechanical properties. READ MORE

  6. 4. On deoxidation practice and grain size of austenitic manganese steel

    Author : Dimitrios Siafakas; Anders Jarfors; Taishi Matsushita; Johan Nils Ahlström; Jönköping University; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hadfield steel; deoxidation; grain size; inoculation; particles; carbides; oxides; Hadfield stål; desoxidering; kornstorlek; ympning; partiklar; karbider; oxider;

    Abstract : The exceptional wear resistance and work hardenability, place Hadfield steel as one of themost important materials for manufacturing cast components used in the mining, crashing,drilling, and excavation industries. In all metallic alloys used for component casting, themechanical properties are highly influenced by the microstructure of the material. READ MORE

  7. 5. Study of Non-metallic Inclusion in Alloy 825

    Author : Hans Kellner; Andrey Karasev; Pär Jönsson; Guozhu Ye; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Alloy 825; FeTi70R alloy; non-metallic inclusions; inclusion distribution; clusters; electromagnetic and gas stirring; ladle treatment; electrolytic extraction; stirring directions; Alloy 825; FeTi70R legering; icke-metalliska inneslutningar; inneslutnings fördelning; kluster; elektromagnetisk och gas omrörning; skänkugnsbehandling; elektrolytisk extraktion; omrörningshåll; Metallurgical process science; Metallurgisk processvetenskap; Steel Forming and Surface Engineering;

    Abstract : It is well known that inclusions affect the properties of steels and alloys. Therefore, it is important to understand what type of inclusions that exist and how they behave and especially with a focus on large size inclusions. READ MORE
