Are superior in processability the high Al content steel sheet and its production mannered

摘要

The present invention provides a high Al-content steel sheet having an excellent workability and a method of production of the same at a low cost by mass production, a high Al-content metal foil and a method of production of the same, and a metal substrate using a high Al-content metal foil, that is, a high Al-content steel sheet having an Al content of 6.5 mass% to 10 mass%, the high Al-content steel sheet characterized by having one or both of a {222} plane integration of an ±-Fe crystal with respect to the surface of the steel sheet of. 60% to 95% or a {200} plane integration of 0.01% to 15% and a method of production of the same, a high Al-content metal foil and a method of production of the same, and a metal substrate using a high Al-content metal foil.
