Abstract

Nach der EMK‐Methode werden die thermodynamischen Eigenschaften des Systems untersucht.

Thermodynamic optimization of the Mn–Ni system

“…The mixing enthalpies of liquid were investigated with high temperature calorimetry for the entire range of composition at 1500 8C by Batalin et al [15]. In the present work, the standard enthalpies of formation of the compounds in the Mn-Ni system are predicted using the revised Miedema model of Niessen et al [19], in kJ/mol of atoms: bMnNi, K12.33; MnNi 2 , K10.22; MnNi 3 , K7.98.…”

“…Ding et al [11] also considered that only one phase existed in the equiatomic region between 500 and 650 8C. The activities of Mn in the temperature range 1189-1900 K were determined by Pozharskaya et al [12], and Eremenko et al [13], Pratt and Ahmad [14], Batalin et al [15], and Jacob [16], respectively. Venkataraman and Hajra [17] measured the activity of Mn and Ni over the temperature range 950-1348 K by a galvanic cell technique, using fluoride and oxide electrolytes.…”

Thermodynamic Description of the Mg-Mn, Al-Mn and Mg-Al-Mn Systems Using the Modified Quasichemical Model for the Liquid Phases

“…Thermal analysis [18] Knudsen cell, 1247°C [22] EMF, 1297°C [21] Calculated, 1247°C, this work Calculated, 1247°C [19] …”

“…The activities of the components in the Al-Mn melt measured by Batalin et al 21) and Chastel et al 22) have been compared with the current calculation as well as the 19) in Fig. 6.…”

“…Esin 20) measured calorimetrically the enthalpy of mixing of liquid Al-Mn at 1353 C. Batalin 21) measured the activity of Al in liquid Al-Mn alloy at 1297 C by EMF measurement and Chastel et al 22) measured the same at 1247 C using Knudsen cell. Kubaschewski and Heymer 23) and Meschel and Kleppa 24) measured the enthalpy of formation of some of the solid AlMn alloys using, respectively, reaction calorimetry and direct synthesis calorimetry.…”
