“…Au esaslı alaşımlar iyi mekanik ve termal özellikleri ile korozyon tutarlılığıyla tanınır ve potansiyel aday olarak kabul edilebilir. Bu sistemler arasında Au-In-Sn-Zn dört bileşenli alaşım sistemi dikkate alınmış ve yukarıda sözü edilen sıvı Au-In-Sn-Zn alaşımlarının karışımının kısmi ve integral entalpileri 500°C'de beş adet üçlü kesit: In 0,800 Sn 0,100 Zn 0,100 , In 0,550 Sn 0,225 Zn 0,225 , In 0,100 Sn 0,800 Zn 0,100 , In0,450Sn0,450Zn0,100 ve In0,225Sn0,550Zn0,225 için ölçümler yapılmıştır [9]. Yukarıda bahsedilen alaşıma ek olarak, elektronik için mevcut ve en umut verici olan kurşunsuz lehimlerin birçoğu, düşük oranda gümüş ve / veya bakır ilave edilmiş düşük erime dereceli bir baz alaşım olarak kalay veya kalay ve indiyum içerir.…”

“…Bu durum, lehimleme esnasında ve lehimlenmiş cihazların çalışması sırasında ortaya çıkan işlemlerin anlaşılmasına yönelik olarak, iki adet Ag-Cu-Ni-Sn ve Ag-In-Pd-Sn dörtlü sistemin ve üç adet In-Sn-Zn, In-Pd-Sn ve Ag-In-Sn üçlü sisteminin önemine dikkat çekmektedir. Son zamanlarda, Pb-içermeyen Au-In-Sn-Zn alaşımlarının ikili ve üçlü termodinamik özellikleri ile ilgili literatür araştırması, Boulouiz ve Sabbarın yayınlarında ayrıntılı olarak bulunabilir [9]. Yapılan literatür araştırmasında, Au-In-Zn üçlü ve Au-In-Sn-Zn dörtlü sistemleri için karışımın entalpileri ve kısmi entalpileri hakkında literatürde pek fazla veri elde edilememiştir.…”

Modeling of micro tools using analytical methods  Effect of spindle speed on stability diagrams  Calculation of tool vibration during micro milling operations In this study, Chou's general solution model (GSM) and the geometric models were applied to six components liquid and quaternary, ternary liquid alloys for high temperature. In all geometric models, the enthalpy and partial enthalpies of mixing of liquid Ni-Cr-CoAl -Ti-Cu of six components for the cross sections, xNi/xCr =1, xNi/xCo =1, xCr/xCo =1, r=xAl / xTi , Pb-free quaternary Au-In-Sn-Zn alloy for the cross section, xIn / xSn = 2, xSn / xZn = 1 and ternary In-Pd-Sn alloy for the cross section, xIn/xSn =1 have been evaluated at the temperatures 2000 K, 773 K and 1173 K, respectively, in order to compare with the experimental results. Generally speaking, it is seen that there is an agreement between the results of geometric models and those of thre experimental results. Figure A. For r=6, partial excess energy of Cu for the mixing in the liquid Ni-Cr-CoAl -Ti-Cu system at 2000 K using the different models. Purpose: In this study, Chou's general solution model (GSM) and the traditional geometric models were applied to liquid Ni-Cr-CoAl -Ti-Cu, Au-In-Sn-Zn and In-Pd-Sn alloys for high temperature. Theory and Methods: In this study, some models known as geometric model Chou's general solution method, Kohler, Muggianu, Toop and Colinet models were used to calculate Gibbs energy and enthalpies of three, four and six component liquid alloys. Results: The results obtained from the models used in this study were found to be mutually compatible. Conclusion: Generally speaking, it was understood that almost all of the models gave results close to the experimental results, but the GSM model supported other models in all models.

“…[25] The closed equations used in the calculations of the enthalpies associated with the quaternary geometric models can be found in References 26,27,29,30. The calculated values are compared to those obtained in the experiments. [27,28] Use of a symmetrical model when an asymmetrical model is more appropriate can often give rise to errors. According to the two categories mentioned above, the four different extrapolation models in the present study were used to calculate the enthalpy of mixing in the ternary system which contains three binary systems, in the quaternary system which contains six binary systems, in the six-component systems which contains fifteen binary systems and the information of all these binary systems were investigated and the data were gathered in literature before using the models.…”

In the present study, the enthalpies of mixing associated with the liquid phase in Ni-Cr-Co-AlTi-Cu, Au-In-Sn-Zn, and In-Pd-Sn systems at a temperature of 2000 K (1727°C) through the six components, ternary, and quaternary geometric models are calculated. The values calculated from different geometric models are compared with those obtained in the experiments. In this respect, the results of some thermodynamic prediction methods were applied to the six-component Ni-Cr-Co-Al-Ti-Cu system, the quaternary alloy Au-In 0.45 -Sn 0.45 -Zn 0.1, and the subsystem ternary alloy In-Pd-Sn in the present study in order to analytically determine the integral properties associated with the six-component alloy systems in the liquid phase. The Chou's general solution model and the traditional models of Toop, Colinet, Muggianu, and Kohler were included in the calculation for comparison and discussion. A comparison among the results of the models and experiments carried out for ternary and quaternary systems displays good mutual agreement.
