摘要
The present invention relates to a method and apparatus for quantitatively measuring a metal phase contained in a galvanized layer by X-ray diffractometry, and a method of producing a galvanized steel sheet by using the method and apparatus. The diffracted X-ray intensity from a metal phase contained in the galvanized layer is increased to improve measurement accuracy, thereby permitting application to on-line measurement. The diffracted X-rays from the metal phase are measured over a predetermined range on a Debye ring, or measured at a plurality of positions on the Debye ring to increase the diffracted X-ray intensity, thereby improving measurement accuracy. The X-ray beam produced by an X-ray source is compressed and made parallel and monochromatic by a multilayer film mirror to increase diffracted X-ray intensity, improving measurement accuracy. Particularly, the present invention is applied to measurement of the degree of alloying of hot-dip galvanization.
