Keywords: resistivity, conductivity, alloy, high temperature

Electrical resistivity characterization technology is a typical method for studying the phase transformation behavior of metals and alloys, such as analyzing carbon motion behavior in advanced steels, studying alloy precipitation kinetics, and characterizing the pre phase transformation behavior of shape memory alloys. The resistivity is very sensitive to these phase transition behaviors, and using resistivity methods to study the kinetics of alloy precipitation is also an important means to monitor the entire aging precipitation process of alloys. Meanwhile, through the evolution law of resistivity, a clear judgment can be madeGPDifferent stages such as zone, precipitation incubation time, precipitation end (large precipitation amount), and maturation process. For all precipitation strengthened alloys, resistivity data can provide important process guidance. In addition, the appearance of nano domains during the pre phase transition process leads to modulus softening and relaxation internal friction behavior, especially in the early stage of phase transition, which is difficult to observe with electron microscopy. However, the appearance of nano domains is manifested as an increase in electrical resistivity. Therefore, the evolution process of temperature and domain area at which nano domains appear can be clearly characterized through the evolution of electrical resistivity.
