  1. 16. On Surface Characteristics and Microstructural Development of Soft Magnetic Composite Powder and Components

    Author : Christos Oikonomou; [2015]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; X-ray photoelectron spectroscopy; compaction; annealing; X-ray diffraction; soft magnetic composites; high resolution scanning electron microscopy; surface layers; magnetic testing; powder metallurgy; depth profiling; electron backscatter diffraction; focused ion beam; thickness determination; energy dispersive X-ray spectroscopy; microstructure;

    Abstract : Soft Magnetic Composite (SMC) products manufactured by traditional Powder Metallurgical (PM) techniques, are strong candidate materials for electromagnetic applications. Their advantages are based on cost and energy efficient production methods, shape complexity realization and uniquely uniform and isotropic three dimensional (3D) magnetic properties. READ MORE

  2. 17. Generation and Applications of Short-Pulse X-ray Radiation

    University dissertation from Atomic Physics, Department of Physics, Lund University

    Author : Michael Harbst; Lunds universitet.; Lund University.; [2005]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; egenskaper termiska och mekaniska ; Kondenserade materiens egenskaper:struktur; crystallography; phase equilibria; Material science; Condensed matter:stucture; thermal and mechanical properties; time-resolved; X-ray diffraction; kristallografi; fasjämvikt; Material technology; Materiallära; materialteknik;

    Abstract : This thesis summarizes work using hard X-ray radiation on nanosecond and picosecond timescales. The focus is on the experimental part including detailed descriptions of setups for laser pumped - X-ray probe experiments. X-ray diffraction is sensitive to structural properties on the length scale of chemical bonds. READ MORE

    Abstract : Popular Abstract in Swedish Snabba fenomen, som inträffar efter laserexcitation, har studerats med tidsupplöst röntgendiffraktion (TXRD). I de flesta experimenten har en ljuspuls från en femtosekundlaser använts för att excitera provet, och dynamiken har undersökts med röntgenljus. READ MORE
