A combination of a quadrupole mass spectrometer and a Knudsen cell was used to study thermodynamic properties such as the activity and phase siagram of a series of alloys. In the present study, heating the knudsen cell in a high vacuum atmosphere to about 1900K was accomplished by resistance radiation from double spiral tungsten filament. The results obtained are as follows.1. Ion intensity thermal analysis of Ag-Mn alloys: Heating and cooling curves of ion intensity of a a component of the alloy were used to detect transformations in the alloy. Temperature and type of invariant reactions in the alloys were determined.2. Thermodynamic study of liquid Ni-Cr-Co alloys: Activities of liquid Ni-Cr-Co alloys were determined by the use of ion intensity ratio-Gibbs Duhem method. It was proved that regular solution assumption was applicable to this ternary solution. 3. Thermodynamic study of Fe-Ta and Fe-Nb alloys: Supplemental study was carried out to the thermodynamic investigation of these alloys.4. Activities were determined in carbon saturated liqued iron-Co and Zn alloys. Activity coefficients and interaction parameters were derived. The details are still under investigation.

四极质量光谱仪和knudsen细胞的组合用于研究热力学特性，例如一系列合金的活性和相位。在本研究中，通过双螺旋钨丝从高真空气氛中加热Knudsen细胞至约1900K。获得的结果如下1。 AG-MN合金的离子强度热分析：合金A成分的离子强度的加热和冷却曲线用于检测合金中的转化。确定合金中不变反应的温度和类型。2。液体NI-CR-CO合金的热力学研究：液体NI-CR-CO合金的活性是通过使用离子强度比duhem方法确定的。事实证明，常规溶液假设适用于该三元溶液。 3。Fe-Ta和Fe-NB合金的热力学研究：对这些合金的热力学研究进行了补充研究。4。活性在碳饱和的液化铁o和Zn合金中确定。得出了活性系数和相互作用参数。细节仍在调查中。
