  2. 6. Assessment of acetabular cup wear with computed tomography and influence of surface roughness on wear of materials for hip prostheses

    Author : Anneli Jedenmalm; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hip prostheses; Computed Tomography; Surface roughness; UHMWPE; Wear; Coating; γ-irradiation; pin-on-disc; hip simulator; Other materials science; Övrig teknisk materialvetenskap;

    Abstract : Over one million hip prostheses are implanted in patients worldwide each year and the need is increasing as the patient group of younger and more active patients is increasing. Many parameters affect the longevity of the implant, where aseptic loosening caused by wear debris is the most common reason for revision. READ MORE

  4. 7. Thermodynamic Database for Zirconium Alloys

    Author : Rosa Jerlerud Pérez; Bo Sundman; Arthur Motta; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Zirconium alloys; thermodynamic equilibrium; thermodynamic properties; binary system; ternary system; Gibbs energy; Thermo-Calc; Calphad; binary system; ternary system; Other materials science; Övrig teknisk materialvetenskap;

    Abstract : For many decades zirconium alloys have been commonly used in the nuclear power industry as fuel cladding material. Besides their good corrosion resistance and acceptable mechanical properties the main reason for using these alloys is the low neutron absorption. READ MORE

  6. 9. Studies of Steel/Slag Equilibria using Computational Thermodynamics

    Author : Lina Kjellqvist; Bo Sundman; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; steel slag equilibria; thermodynamic modelling; thermodynamic assessment; CALPHAD; phase diagram; Thermo-Calc; Other materials science; Övrig teknisk materialvetenskap;

    Abstract : The main focus in the present work concerns calculations on steel/slag equilibria. Thermodynamic software and databases are now powerful and accurate enough to give reliable results when applied to complex metallurgical processes. One example is the decarburization process of high alloyed steels. READ MORE

  7. 10. Modeling the microstructural evolution during hot working of C-Mn and Nb microalloyed steels using a physically based model

    Author : Linda Lissel; Stefan Jonsson; Bertil Ahlblom; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; austenite; modeling; hot deformation; microstructure evolution; static recrystallization; dynamic recrystallization; metadynamic recrystallization; Other materials science; Övrig teknisk materialvetenskap;

    Abstract : Recrystallization kinetics, during and after hot deformation, has been investigated for decades. From these investigations several equations have been derived for describing it. The equations are often empirical or semi-empirical, i.e. READ MORE
