Body text

In this solution, in-situ X-ray diffraction measurement was applied to analyze the growth behavior of Fe-Zn intermetallic compounds at initial stage (~ a few 10 seconds) of gaalvannealing process. The data of change of the X-ray diffraction pattern from zinc coating indicated the dependence of the composition of the coatings on the growth behavior of Fe-Zn intermetallic compounds in the galvannealing process.

Technique

In this experiment, the measurement of the X-ray diffraction from galvanized steel were carried out heating the samples up to T = ~460C by infrared beam heater. The time dependence of 1D profiles of the diffraction extracted by a receiving slit (2.5400mm) were continuously recorded on imaging plates set behind the receiving slit scanning in the horizontal direction. Using high energy X-ray (28KeV), the initial stage (~10sec)of the growth behavior of Fe-Zn intermetallic compounds at the interfaces between the Zn coatings and substrates was successfully observed.
