| Project Background

The melting point is the phase transition temperature at which a metal changes from a solid state to a liquid state. It directly reflects the strength of the binding energy between atoms and determines the thermal stability and processing window of the material in a high-temperature environment. By accurately monitoring the endothermic peak of the material's phase transition, the melting point, melting range, and the influence of impurities can be analyzed. This technology directly serves the process optimization of electronic packaging solders, the safety assessment of aerospace superalloys, and the parameter calibration of additive manufacturing. It is a core quality control link in the high-end manufacturing field.

| Project Overview

In this test, the differential scanning calorimetry (DSC) method is used for measurement: an appropriate amount of metal sample (5-10 mg) is placed in a sealed crucible, and the temperature is programmed to increase at a rate of 5-20 °C/min under an inert atmosphere. By monitoring the heat flow difference between the sample and the reference substance in real-time, parameters such as the melting point, melting range, and enthalpy of fusion can be obtained simultaneously. It is suitable for process optimization and failure analysis of materials such as solders and superalloys.
