摘要： A method of forming an Al-Zn-Si-Mg alloy coating on a steel strip includes dipping steel strip into a bath of molten Al-Zn-Si-Mg alloy and forming a coating of the alloy on exposed surfaces of the steel strip. The method also includes controlling conditions in the molten coating bath and downstream of the coating bath so that there is a uniform Al/Zn ratio across the surface of the coating formed on the steel strip. An Al-Zn-Mg-Si coated steel strip includes a uniform Al/Zn ratio on the surface or the outermost 1-2μm of the Al-Zn-Si-Mg alloy coating.

摘要： The present invention relates to a hot press forming steel plate made of a composition comprising: 0.3-1.0 wt % of C; 0.01-4.0 wt % of Mn; 1.0-2.0 wt % of Si; 0.01-2.0 wt % of Al; 0.015 wt % or less of S; 0.01 wt % or less of N; and the remainder being Fe and unavoidable impurities. Further, the present invention relates to a method for manufacturing the hot press forming steel plate, characterized by comprising the steps of: heating, to between 1100 and 1300°C, a steel slab having the composition; performing hot rolling finishing between an Ar3 transformation point and 950°C; and performing winding between MS and 720°C. Further, the present invention relates to a hot press formed member characterized by having the composition, and having a dual phase microstructure made of bainite and residual austenite. In addition, the present invention relates to a method for manufacturing the hot press formed member, characterized by comprising the steps of: heating the steel plate having the composition to a temperature of an Ac3 point or higher; hot press molding the heated steel plate; performing cooling at a cooling speed of 20°C/sec or higher to a temperature between MS and 550°C; and performing a heat treatment in a heating furnace between MS and 550°C.

摘要： A current collector is covered with sodium metal through: (1) a step of applying a sodium dispersion containing sodium metal and at least one substance selected from the group consisting of an imide salt and a binder, on a current collector in an inert gas environment (with an oxygen concentration of not more than 0.01% and a dew point of not more than -10°C), followed by heating and drying; (2) a step of pressure bonding a piece of solid sodium metal having a surface which exhibits a metallic luster onto a current collector in the aforementioned inert gas environment; (3) a step of vapor-depositing sodium metal on a current collector in a reduced pressure environment; or (4) a step of immersing a current collector having a surface fired at a temperature ranging from 150 to 300°C in molten sodium metal after removing a coating film which is generated on a surface and formed from impurities, in the aforementioned inert gas environment.
