摘要： PROBLEM TO BE SOLVED: To provide a hot-pressed member capable of reliably obtaining excellent coating adhesiveness, and a method for manufacturing the same.
SOLUTION: The hot-pressed member has a Zn-Fe alloy layer, a Si-containing layer, and a ZnO layer in this order on the surface of a steel sheet constituting the member. In the method for manufacturing the same, a hot-dip galvannealed steel sheet having an Si-containing compound layer on its surface is heated at the temperature of 800-1,000°C for the time >3 minutes and ≤15 minutes to execute the hot press. Zn in a plating layer and Fe in the steel sheet are subjected to mutual diffusion in an interface between the plating layer and the base steel sheet, and a Zn-Fe alloy layer is formed thereby. Zn in the upper layer portion of the plating layer passes through the Si-containing compound layer and diffused to the surface, and is reacted with O in the atmosphere to form a ZnO layer on the Si-containing compound layer.

摘要： PROBLEM TO BE SOLVED: To provide a hot-dip Al-Zn plated steel sheet which has superior press formability, and to provide a method for manufacturing the same. SOLUTION: An Al content in the plated film is 20-95 mass%. A Si content in the plated film is 5 mass% or more with respect to the Al content. The plated film includes an upper layer and an alloy phase existing in the interface between the upper layer and a base steel sheet, and the upper layer contains 3 mass% or more non-dissolved Si with respect to the Al content in the plated film. Thus, by increasing the amount of the non-dissolved Si, the number of crack increases, the aperture width of each crack is decreased. Then, the aperture is difficult to become a starting point of the peeling of the plated film due to sliding, and as a result, the press formability is enhanced. COPYRIGHT: (C)2010,JPO&INPIT
