Abstract

Highly reliable measurement of degree of alloying of galvannealed steel sheets is carried out in order to fully control the continuous hot-dip galvanizing and galvannealing process on the basis of evaluation of a combination of two or more X-ray diffraction characteristics. Exact degree of alloying can be estimated without regard to fluctuations in the particulars of the material, the process conditions and the type of the product obtained.
