Abstract
A method of measuring a thickness of a Fe—Zn alloy phase included in the Fe—Zn alloy coating of the galvannealed steel sheet includes: an X-ray irradiation process of irradiating the galvannealed steel sheet with the incident X-rays; and an X-ray detection process of detecting the diffracted X-rays obtained in the X-ray irradiation process, derived from a Γ·Γphase, a δphase, and a ζ phase included in the Fe—Zn alloy coating with a crystal lattice spacing d of 1.5 Å or higher.
