Abstract
Abstract Thermal analysis methods have a wide range of applications in the examination of phase equilibria, phase transformation behavior and synthesis, and environmental reactions in metallic systems. Among the variety of thermal analysis methods, the presentation focuses on Differential Thermal Analysis (DTA), Differential Scanning Calorimetry (DSC), Thermogravimetric Analysis (TGA), Flash DSC, and Differential Mechanical Analysis (DMA). With properly calibrated instruments, important thermodynamic properties can be determined such as phase transition temperatures, enthalpy of mixing, synthesis reactions and intermetallic phase formation, heat capacity and expansion coefficients. The implementation of both isothermal and continuous temperature scanning protocols represents an effective experimental strategy in the determination of phase reaction kinetics. In order to illustrate the capabilities of thermal analysis methods, several selected examples are highlighted for phase diagram determination in binary and higher-order alloys, the formation and thermal stability of metallic glass, oxidation reactions, solidification during joining, shape memory behavior, and non-equilibrium melting characteristics.
