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

    University essay from KTH/Materialvetenskap

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

    Abstract : 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. 3. Regulation of Nitrogen Content in High Alloyed Stainless Steels during the AOD Process

    University essay from KTH/Materialvetenskap

    Author : Hanna Englund; Henrietta Isaksson; [2019]
    Keywords : ;

    Abstract : As a final step in the argon oxygen decarburisation (AOD) process, argon- and nitrogen gas is blown through the melt. To regulate the nitrogen content in the steel melt during this step a reliable model is needed. READ MORE

  5. 4. Built-up edge formation in stainless steel milling

    University essay from KTH/Materialvetenskap

    Author : Axel Andersson; [2017]
    Keywords : Built-up edge; milling; stainless steel; tool wear;

    Abstract : Milling tests were performed in stainless steel to investigate the formation of built-up edge (BUE). Three variants of tests were conducted which were divided as high-, medium, and low temperature milling tests. These tests were run in the austenitic stainless steel SS2343. READ MORE

  6. 5. Bow design for operation in brash ice

    University essay from KTH/Marina system

    Author : Kjell Teepen; [2017]
    Keywords : ;

    Abstract : Using a vessel for public transport can possibly save large amounts of time in a city as Stockholm. The transport is easy during the period of the year where there is no ice cover on the waters, however during the time when there is ice, the vessels used face more extreme conditions. READ MORE
