“ExTHERM”: the interactive support package of experimental thermodynamics

The presented program package “ExTHERM” consists of three parts: (i) cETD, a simple interactive open data bank module covering all types of metal alloys (over 150 binary phases and some ternaries), (ii) cMod, a module for algebraic conversion among different representations of excess data, and (iii) cM3_(KMS/ EMF/HTC), three interactive evaluation units suitable for overall best fits of experimental investigations expandable to mass spectrometric (KMS), EMF, and calorimetric investigations (HTC). The concept is based upon the multi-component TAPS (Thermodynamically Adapted Power Series) concept of excess quantities covering all types of solutions, includingn liquid alloys showing short range ordering. The data bank is based upon the Hultgren data of binary systems and on new experimental data. Individual supplements may be performed easily. The conversion module employs a modular concept procedure which makes the conversions independent of the actual system data. For all software modules contact the author.
