2. 1. 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

5. 3. Cation adsorption properties of substituted kraft fibres : an experimental and thermodynamic modelling study

   Author : Ola Sundman; Lars-Olof Öhman; Per Persson; Janne Laine; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Kraft fibres; Donnan equilibria; ion exchange; acid base properties; potentiometric titrations; thermodynamic modelling; NPEs; GaAl12 7 ; EXAFS; Chemistry; Kemi;

   Abstract : Acid/base and metal ion adsorption properties have been investigated for a range of chemically modified bleached Kraft fibre materials (pulps). The studies were performed via potentiometric titrations, Flame Atomic Absorbtion (and Emission) Spectroscopy, Inductively Coupled Plasma Optical Emission Spectroscopy and Extended X-ray Absorbtion Fine Structure measurements.

6. 4. Phase equilibria and thermodynamic properties of high-alloy tool steels : theoretical and experimental approach

   Author : Johan Bratberg; John Ågren; Bengt Hallstedt; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; thermodynamic modelling; thermodynamic calculations; tool steels; high-speed steels; CALPHAD; Other materials science; Övrig teknisk materialvetenskap;

   Abstract : The recent development of tool steels and high-speed steels has led to a significant increase in alloy additions, such as Co, Cr, Mo, N, V, and W. Knowledge about the phase relations in these multicomponent alloys, that is, the relative stability between different carbides or the solubility of different elements in the carbides and in the matrix phase, is essential for understanding the behaviour of these alloys in heat treatments.

7. 5. Corresponding States Correlations for the Prediction of Thermodynamic Properties of Refrigerants

   Author : Maria Sörner; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; refrigerant mixtures; corresponding states; parameter estimation; equation of state; refrigerants; thermodynamic properties;

   Abstract : When process equipment such as separation units, heat pumps, and refrigeration systems are simulated or designed, physico-chemical properties of the fluids involved must be known. The outcome of the simulation or design depends on the accuracy of the correlations used in the prediction of physico-chemical data, so it is of the utmost importance that the correlations used correctly describe the properties of the fluids.
