  1. 1. Residual Products in the Steel Industry Used for Briquetting

    Kandidat-uppsats, KTH/Materialvetenskap

    Författare :Alexander Eriksson; Linn Isaksson; Jacob Lilliebjörn; [2023]
    Nyckelord :;

    Sammanfattning : This report looks at the implementation of briquetting in the Swedish steel industry. Briquetting is a process in which residual products are mixed and compressed into a brick-like body in order to be added to the melt in a furnace. This report investigates the type of materials commonly used in briquetting as of today. LÄS MER

  3. 2. Simulation and Experimental Based Hardenability Evaluation of Chromium Alloyed Powder Metal Steels

    Master-uppsats, KTH/Materialvetenskap

    Författare :Atharva Kotasthane; [2023]
    Nyckelord :Hardenability; Martensite; Simulation Modelling; Microhardness; Microstructure; Härdbarhet; Martensit; Simuleringsmodellering; Mikrohårdhet; Mikrostruktur;

    Sammanfattning : Powder metallurgy is a branch of metal forming technology where metal powders are used to manufacture parts and components. It is a flexible and economical technique for manufacturing complicated shapes. This present work focuses on press and sinter technology and forms a part of Höganäs’s efforts of modelling hardenability through quenching. LÄS MER

  4. 3. Apparent density for water atomized low-carbon steel powder

    Master-uppsats, KTH/Materialvetenskap

    Författare :Simon Lindström; [2023]
    Nyckelord :;

    Sammanfattning : Carbon content does not affect the apparent density for water atomized iron powder monotonically. At low carbon content, around 0.1 wt %, apparent density is higher than a similar powder with 0.3 wt % carbon. LÄS MER

  5. 4. Iron Pieces from The Copper Wreck : An archaeometallurgical analysis of iron bars, billets and osmund iron found in Gdansk, Poland

    Kandidat-uppsats, KTH/Materialvetenskap

    Författare :Mikael Ghaysari; Benjamin Tiberghien; Maximilian Åkerblom Jonsson; [2022]
    Nyckelord :The Copper wreck; W5; Miedsiowiec; Osmund; Slag analysis; SEM; EDS; LOM; Medieval iron production; Blast furnace; Indirect reduction; Direct reduction; Kopparvraket; W5; Miedsiowiec; Osmund; Slagg; SEM; EDS; LOM; Medeltida järnproduktionen; Masugn; Indirekt reduktion; Direkt reduktion;

    Sammanfattning : The topic of osmund iron is of great interest in both historical and metallurgical perspective. Between the 14th and the 17th century osmund iron was exported extensively from Sweden but it has been difficult to characterize and confirm what exactly osmund iron is. LÄS MER

  7. 5. Biogeochemistry and Peat Properties of Restored Peatlands

    Master-uppsats, SLU/Dept. of Forest Ecology and Management

    Författare :Pelle Belaieff Kronborg; [2022]
    Nyckelord :Drainage; Bulk density; Nitrogen; Carbon; Stable isotopes;

    Sammanfattning : Globally, peatlands comprise the most important soil organic carbon pool storing approximately one third of all terrestrial soil carbon. Drainage can turn peatlands to net sources of carbon dioxide. Peatlands have historically been drained to increase the productivity of agriculture and forestry. LÄS MER
