  2. 1. Quantitative electron probe X-ray microanalysis of biological specimens

    Author : Godfried M. Roomans; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The application of quantitative methods in electron probe X-ray microanalysis of biological specimens expands the scope of this technique. Accurate quantitation in biological X-ray microanalysis is not easy and a number of difficulties is typical for biological specimens. READ MORE

  6. 4. Development of Cermet Microstructures during Sintering and Heat-Treatment

    Author : Jenni Zachrisson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; APFIM; EELS; cemented carbides; quantitative microanalysis; gradients; N ; TEM; EFTEM; hardmetals; EDX; Ti C; light elements;

    Abstract : The work presented in this thesis is concerned with the microstructure of Ti(C, N) based cermet materials used in cutting tool applications. Several techniques have been used to study the microstructure of cermets, in particular transmission electron micro-scopy in combi-na-tion with energy dispersive X-ray analysis and electron energy-loss spectroscopy, energy-filtered transmission electron micro-scopy, atom-probe field-ion microscopy and scanning electron microscopy.

  7. 5. Development of Composition Gradients in Cemented Carbides

    Author : Robert Frykholm; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; EPMA; DICTRA; functionally graded materials; gradient sintering; diffusion; APFIM; thermodynamic modelling; SEM; surface zones;

    Abstract : This thesis concerns the formation of tough surface zones, depleted of cubic carbo-nitrides, in cemented carbides. Several materials with varied phase compositions, binder phase volume fraction, and carbon content have been investigated. READ MORE
