The nickel layer includes an upper layer portion which is in contact with the chromium-based surface treatment layer and contains Ni of 90 mass % or more among metal elements, and a lower layer portion which is in contact with the rolled steel foil and contains Ni of less than 90 mass % among the metal elements and Fe. polar density in a reverse pole figure of the nickel layer in a rolling direction is 3.0 to 6.0. The nickel layer has a sub-boundary which is a boundary between two crystals having a relative orientation difference of 2° to 5°, and a large angle boundary which is a boundary between two crystals having the relative orientation difference of equal to or more than 15°. The average value of a ratio L5/L15 between a boundary length L5 which is the length of the sub-boundary, and a boundary length L15 which is the length of the large angle boundary, is equal to or more than 1.0.

In a case of performing a glow discharge spectrometry, at an interface between the oxide layer and the metal layer, an emission intensity of Fe atoms is 20% or less of the maximum emission intensity of the Fe atoms, and the emission intensity of Ni atoms is 20% or less of the maximum emission intensity of the Ni atoms. In addition, a first range in which the emission intensity of Zn atoms is 60% or higher of the maximum emission intensity of the Zn atoms and a second range in which the emission intensity of the Ni atoms is 60% or higher of the maximum emission intensity of the Ni atoms overlap.

摘要： Exemplary embodiments of the present invention can provide a method for producing hot dip galvannealed steel sheet which exhibits high strength, high ductility, and a significant degree of alloying. Such exemplary method can be applied to, e.g., a pickled hot rolled steel sheet or an annealed and pickled cold rolled steel sheet containing between about 0.02% and about 0.2% C and between about 0.15% and about 2.5% Mn, and may include one or more procedures for rinsing the sheet, preplating the sheet with Ni, rapidly heating the sheet in a nonoxidizing atmosphere to a sheet temperature of about 430° C. to 500° C., then hot dip plating the sheet in a galvanizing bath containing between about 0.05% and about 0.2% Al, and then immediately heating the sheet rapidly for an alloying treatment. Such exemplary method can provide an improved alloying speed, improved plating appearance and better plating adhesion.
