  1. 11. Separate Calcination in Cement Clinker Production : A laboratory scale study on how an electrified separate calcination step affects the phase composition of cement clinker

    Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för tillämpad fysik och elektronik

    Författare :Amanda Vikström; [2021]
    Nyckelord :Cement; Cement clinker; Calcination; Separate calcination; Electrification; CO2 atmosphere; Product quality; Product characterization; XRD; HT-XRD; Rietveld refinement;

    Sammanfattning : Cement production is responsible for around 7% of the global anthropogenic carbon dioxide emissions. More than half of these emissions are due to the unavoidable release of carbon dioxide upon thermal decomposition of the main raw material limestone. LÄS MER

  3. 12. Machine learning for the prediction of duplex stainless steel mechanical properties : Hardness evolution under low temperature aging

    Kandidat-uppsats, KTH/Materialvetenskap

    Författare :Baptiste Giard; Sofia Karlsson; [2021]
    Nyckelord :Duplex Stainless Steel DSS; Machine Learning; Phase Separation; Me- chanical Properties; Alloying; Duplexa rostfria stål; Maskininlärning; Fasseparation; Mekaniska Egenskaper; Legering;

    Sammanfattning : Duplex stainless steels, DSS are stainless steels that consist of the two phases austenite and ferrite.  The DSS have superb properties and are widely used in industries such as nuclear power and in pressure vessels, pipes and in pipelines.  The use of DSS are limited due to embrittlement which occurs at temperatures from 250 to 550 oC.

  4. 13. Develop Optimization Model for Spheroidal Graphite Iron

    Master-uppsats,

    Författare :Rehman Babar; [2020]
    Nyckelord :;

    Sammanfattning : The main motivation behind this study is to develop a methodology to generate surrogate model coefficients for parametrized Spheroidal Graphite Iron (SGI) for thermal expansion and Young’s modulus response. To accomplish this objective, a 3D model was created by Abaqus, and Python was used for developing the script. LÄS MER

  5. 14. Wireless Power and Data Transfer in Industrial Nutrunners

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Simon Carlsson; [2020]
    Nyckelord :;

    Sammanfattning : Wireless power and data transfer systems are experiencing an ever-growing consumer and industrial adoption. Its use in common devices has made the technology more accessible to people, but seldomly does it replace a physical connection inside a product. LÄS MER

  7. 15. Casting and Characterization of Advanced High Strength Steels

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Författare :Daniel Hedman; [2020]
    Nyckelord :AHSS; characterization; casting; parlite; austenite; martensite; ferrite; grain size;

    Sammanfattning : The Latin American steel making company Ternium S.A. aims to develop and produce a new type of advanced high strength steel (AHSS) in which the main alloying elements are carbon, aluminium, manganese, and silicon. LÄS MER
