  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.

  5. 4. Quenching and tempering hardness response of front axle steel beams : Different material properties during quenching and tempering

    University essay from Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Author : Simon Zemui; [2017]
    Keywords : Axle steel beams; hardness; Quenching; tempering;

    Abstract : The aim of this thesis was to investigate what the relation is between as-quench hardness and final surface hardness for steel beams is, depending on what tempering temperature is used. Also explain how chemistry, dimension and microstructure effects the final mechanical properties of the front axle beam. READ MORE

  6. 5. Phase Field modeling of sigma phase transformation in duplex stainless steels : Using FiPy-Finite Volume PDE solver

    University essay from KTH/Materialvetenskap

    Author : Venkata Sai Pavan Kumar Bhogireddy; [2013]
    Keywords : Phase field; Duplex Stainless steels; Sigma phase;

    Abstract : Duplex Stainless Steels (DSS) are used extensively in various industrial applications where the properties of both austenite and ferrite steels are required. Higher mechanical strength and superior corrosion resistance are the advantages of DSS. READ MORE
