Effect of the enamel firing thermal cycle on the microstructure and the hydrogen permeability of enamel-grade steels

摘要

The tendency for fish-scale formation of steel sheets is characterized by the t{sub}0 value directly related to the micro structure of the sheet. During the firing thermal cycle the microstructure undergoes several changes. Changes of the t{sub}0 value and the microstructure were examined for three steel grades. A new conception for the development of steel sheet for vitreous enamelling has also been formulated.
