Heat capacity measurements by differential scanning calorimetry in the Pd–Pb, Pd–Sn and Pd–In systems

Advances in material and friction data for modelling of metal machining

“…A differential scanning calorimeter [177] is used to measure the change in c p with temperature and the transition temperatures, such as phase transformation, while the laser flash method is the most common method for measuring thermal diffusivity a and conductivity k [176]. The coefficient of linear thermal expansion b, which has a direct effect on the thermal elastic deformation and thermally-induced residual stresses, is commonly measured using the mechanical dilatometer method [155].…”

Thermodynamic modeling of the indium-palladium system

“…Calculations of the activity of In is well within experimental error except for the ␣InPd 3 compound, where a large difference exists between measurein fcc give values which lie between the measurements by Bird et al [29] and those by Schaller and Brodowsky. [30] ments by Bryant and Pratt [22] and Perring et al [28] Perring et al's [28] data clearly show significant negative deviation Due to the strongly ordered nature of the InPd(B2) compound, constitutional defects predominate over thermal from the Neumann-Kopp rule for this compound, while the data by Bryant and Pratt are very close to the prediction defects even at high temperatures. The predicted concentrations of constitutional vacancies and antisite defects in the of the Neumann-Kopp rule.…”

“…The B2 Compound metallic compounds In 3 Pd 2 , InPd, ␣InPd 2 , and ␣InPd 3 using differential scanning calorimetry. Recently, Perring et al [28] InPd is a B2 compound with triple defects, i.e., constituremeasured the heat capacities of the solid phases in the tional vacancies on the Pd sublattice and antisite Pd atoms In-Pd system using differential scanning calorimetry. They on the In sublattice, and is described by an (In, Pd) 0.5 (Pd, found that the sample with the nominal composition In 75 Pd 25 Va) 0.5 two-sublattice model.…”

Critical evaluation and thermodynamic modeling of the Pd–Sn system

“…However, the currently optimized thermodynamic parameters can give a very good representation of these heat capacity data. In details, there is inconsistency in the measured heat capacities for the PdSn phase in the literature, the reported data by Perring et al [16] is apparently smaller than that by Bryant et al…”

“…However, the invariant phase equilibria Liquid = fcc_A1 (Pd) + Pd3Sn in the Pd-rich side was unreasonably reproduced by these two sets of thermodynamic parameters [12,13]. In addition, some new experimental data including enthalpy of mixing of liquid [14,15], heat capacities of the intermetallic compounds [3,15,16], enthalpies of formation of compounds [17,18], and a new stable intermetallic phase Pd5Sn7 [19] were not considered in the previous assessments [12,13]. Therefore, there is a need for comprehensive thermodynamic assessments by considering all the thermodynamic property and phase diagram data available in the literature.…”
