Calorimetric measurements in metallurgy: remarks on calibration and some specific problems

Remarks on the role of thermochemical data in intermetallic crystallochemistry

“…• Calorimetric measurements in metallurgy: remarks on calibration and some specific problems [20]. • Thermodynamics of rare earth alloys: systematics and experimental [21].…”

“…For a long time now in our laboratory, an attempt has been made to carry out an investigation of alloy systems and properties by using concerted approaches along a few converging lines (that is, phase diagram investigation [23][24][25], crystallochemistry [26] and thermodynamics [19][20][21][22]), particularly with a view to obtaining a comprehensive description of certain systems. In some cases, it was also possible to use optimization procedures, together with general chemical criteria [27,28].…”

Direct thermodynamic characterization of solid-state reactions by isothermal calorimetry

“…45 Indeed, the demand for calorimeters suitable for investigating the processes occurring in the solid state has been identified in the midst of the 20th century. 46 High temperature isothermal calorimetry has since been extensively applied in metallurgy, [47][48][49] ceramics and cementrelated studies, [50][51][52][53][54] while low temperature experiments have mainly been related to in pharmaceutical studies. 45,[55][56][57] The research involved calorimetric studies of various solid-state reactions i.e.…”

Termodinâmica de primeiros princípios aplicada a ligas de metais de transição

“…A figura 5.1, entretanto, mostra que a variações da ordem de ± =1 kJ mol −1 na energia de formação de um dado composto são observados para todos os compostos dependendo das premissas básicas usadas no cálculo de estrutura eletrônica. Curiosamente está precissãoé da mesma ordem de magnitude da menor estimativa de erro nas técnicas padrões de calorimetria [102] Resultados e Discussões: 03 -Sistemas Binários…”
