Calorimetric data of the silver-titanium system

Due to the experimental difficulties caused, among other factors, by the significant difference in melting points of the components, most of the information on the thermodynamic properties available in the literature has been obtained through computer methods. Therefore, the main goal of this work is to expand the current knowledge about the experimentally determined thermodynamic properties of selected alloys from the Ag-Ti system. Based on the calorimetric results obtained in this study, along with relevant thermodynamic data from the literature, the Ag-Ti phase diagram was reoptimized. The dataset provided includes the results of the experimental study presented in the article and a set of thermodynamic parameters obtained:1. The TXT files with column headers Index, Time (h), Furnace Temperature (°C), Sample Temperature (°C), and Heat Flow (µV) contain calorimetric data from two types of high-temperature drop calorimetry measurements.Files Tab_4_Seria_A_mixing_enthalpy.txt and Tab_5_Seria_B_mixing_enthalpy.txt include data on the enthalpy of mixing for liquid Ag–Ti alloys within the concentration range xTi = 0.02–0.226.Files Tab_6_No_1_formation_enthalpy.txt, Tab_6_No_2_formation_enthalpy.txt, Tab_6_No_3_formation_enthalpy.txt, and Tab_6_No_3A_formation_enthalpy.txt contain results for the enthalpy of formation of the AgTi intermetallic phase determined by the direct synthesis method.2. The Fig_2_DSC_measurement.txt file, with the headers Temp./C, Time/min, DSC/(mW/mg), Sensit./(uV/mW), contains the calorimetric data from the differential scanning calorimetry measurements for the Ag0.43Ti0.57 alloy after annealing.3. The Fig_3_XRD_after_direct_synthesis.xy file contains the XRD diffraction pattern of the alloy obtained during the first high-temperature direct synthesis calorimetry measurement.4. Files: Fig_1_a_SEM_Ag0.43Ti0.57.tiff; Fig_7_a_SEM_Ag.tiffFig_7_b_SEM_TiH2.tiff are SEM images of the materials used for the material preparation (Ag and TiH2) and the obtained alloy after annealing. 5. The Tab_8_thermodynamic_properties.odt file contains the thermodynamic parameters obtained and used for the phase diagram calculations.This work is supported by the National Science Centre, Poland, for funding project no. 2021/43/O/ST8/01291 entitled “Thermodynamic properties and structure of Cu-Mg-Ti and Ag-Mg-Ti alloys and their potential to interact with hydrogen” in the years 2022–2027.
