  1. 1. Impedance of Soft Magnetic Multilayers : Application to GHz Thin Film Inductors

    Författare :Andrey Gromov; KTH; []
    Nyckelord :inductor; impedance; magnetic; eddy currents; FMR;

    Sammanfattning : A theoretical approach to calculating impedance of metallicmagnetic/conductor layered structures is developed. Thefrequency range considered extends to the ferromagneticresonance region of soft magnetic films (of the order of 1GHz). LÄS MER

  3. 2. Hardening Distortions of Serial Produced Gears

    Författare :Anders Olofsson; Stefan Jonsson; Julia Gerth; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hardening distortions; crown wheel; main shaft gear; gear runout; back-face tilt; macrosegregation; ingot casting; continuous casting; case hardening; Materials Science and Engineering; Teknisk materialvetenskap;

    Sammanfattning : Hardening distortions are unwanted changes in shape and dimension that arise during hardening of steel components. Uncontrolled distortions induce random errors to the manufacturing process, and have a strong negative impact on manufacturing costs. LÄS MER

  4. 3. Functional Metallic Glasses

    Författare :Ansar Masood; Lyubov Belova; K. Venkat Rao; Lars Arnberg; KTH; []
    Nyckelord :Bulk Metallic glasses; glass forming ability; soft magnetism; thin films; magnetic properties; magnetic hardening; plasticity; biocompatibility;

    Sammanfattning : For decades, Metallic Glass, with its isotropic featureless structure while exhibiting outstanding mechanical properties was possible only at a high rate of quenching and with at least one dimension in the submicron regime.  This limitation was overcome with the discovery of Bulk Metallic glasses, BMGs, containing three or more elements following the additional two empirical rules of optimum geometric size differences and negative energy of mixing among the constituent elements.

  5. 4. Mechanical Properties of Transition Metal Alloys from First-PrinciplesTheory

    Författare :Li Xiaoqing; Levente Vitos; Mojmír Šob; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The aim of the thesis is to investigate the alloying and temperature effects on the mechanical properties of body-centered cubic (bcc) random alloys. We employ the all-electron exact muffin-tin orbitals method in combination with the coherent-potential approximation. LÄS MER

  7. 5. Towards Subject Specific Aortic Wall Shear Stress : a combined CFD and MRI approach

    Författare :Johan Renner; Matts Karlsson; Toste Länne; Patrick Segers; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fluid mechanics; Strömningsmekanik;

    Sammanfattning : The cardiovascular system is an important part of the human body since it transports both energy and oxygen to all cells throughout the body. Diseases in this system are often dangerous and cardiovascular diseases are the number one killer in the western world. LÄS MER
