  1. 1. Deformation-Induced Martensitic Transformation and Mechanical Properties of Duplex and Austenitic Stainless Steels : A Synchrotron X-Ray Diffraction Study

    Master-uppsats, KTH/Metallografi

    Författare :Sen Lin; [2017]
    Nyckelord :Synchrotron radiation; High energy X-ray diffraction; In situ tensile loading; TRIP steel; Martensite phase transformation;

    Sammanfattning : Metastable austenitic and duplex stainless steels are widely used materials in industrial anddomestic applications, owing to their attractive characteristics such as good corrosion resistanceand favorable mechanical properties. Both types of steel experience enhanced mechanicalproperties during plastic deformation due to the formation of the martensite phase from theparent austenite phase, this is called deformation-induced martensitic transformation (DIMT).

    Nyckelord :Thermoelectric; Thermoelectric figure of merit ZT ; Seebeck effect; Ca3Co4O9; ScN; CrN; ScxCr1-xN; reactive magnetron sputtering; post-annealing; DC magnetron sputtering;

    Sammanfattning : Global warming and developments of alternative energy technologies have become important issues nowadays. Subsequently, the concept of energy harvesting is rising because of its ability of transferring waste energy into usable energy. LÄS MER

  4. 3. Nizamudin Hussain, Performance Limitations and Estimates for Infinite Array Antennas

    Master-uppsats, KTH/Elektroteknisk teori och konstruktion

    Författare :Nizamudin Hussain; [2013]
    Nyckelord :limitations; array antenna;

    Sammanfattning : A novel quantitative measure for predicting the performance of arrays is tested on a few selected wide band arrays. This measure is called the array figure of merit. It is valid for lin-early polarized, infinite planar arrays, which are backed by a perfectly conducting ground plane. LÄS MER

  5. 4. The influence of salt in the formation of carboxylic functionalized mesoporous silica

    Master-uppsats, Lunds universitet/Kemiska institutionen

    Författare :Ruiyu Lin; [2012]
    Nyckelord :Nanokemi; Chemistry;

    Sammanfattning : Popular summary This master thesis was focused on the influence of salt, such as NaCl and CaCl2, in the formation of carboxylic functionalized mesoporous silica materials. Mesoporous silica materials are one type of porous materials with a pore size between 2 and 5 nm (1݊݉ = 0.000000001 ݉ ). LÄS MER
