1. System Description

For steels and other alloy materials, the resistivity is very sensitive to the atom diffusion during tempering. Through the resistance temperature dependent characteristics, the system can accurately capture a series of continuous transformation features such as atoms moving from interstitial position to dislocation, interface enrichment and nucleation, and precipitation from the matrix. These can explain the diffusion kinetics from the perspective of carbon atom(for steel) diffusion activation energy. So,  the in-situ characterization of alloy materials resistance is  an important method to the research works for microstructure transformation principle.
