| Project Background

By precisely tracking the coupled relationship among size, temperature, time, and load, TMA converts the thermomechanical behavior of materials into engineering parameters, which serves as a crucial experimental basis for solving thermal stress failure problems and optimizing thermal processing technologies. TMA is irreplaceable in solving problems related to thermal stress failure, process critical-point control, and the compatibility of multi-material systems.

| Project Overview

The basic principle of the thermomechanical analyzer (TMA) technology is to measure the deformation of a sample during a certain load and temperature program (heating/cooling/constant temperature and their combinations). The following characteristics of materials can be studied using a thermomechanical analyzer:

1. Linear expansion and contraction

2. Glass transition temperature

3. Densification and sintering processes

4. Optimization of heat treatment processes

5. Softening point detection

6. Phase transition processes

7. Research on reaction kinetics.
