Thermoanalytical coupling technique is a kind of method which combines thermoanalytical technique with different detection means

in order to research exactly the characteristics of structure

composition

thermal reaction

etc.of materials and reveal the nature of materials thermodecomposition

especially in the process of the variation of mass and heat and the ingredient of thermodecomposition of metallic materials.In this paper

thermoanalytical technique coupled with several kinds of analytical methods such as differential thermal analysis

differential scanning calorimetry

Fourier infrared spectroscopy and mass spectrometry were emphatically introduced.Taking the research of metallic materials for example

the applications of thermoanalytical coupling technique in the structure and properties of metal materials were described in detail

and the application prospect of thermoanalytical coupling technique was outlooked.
