摘要： PROBLEM TO BE SOLVED: To provide a specified urethane coated aluminum alloy plate superior in press formability. SOLUTION: Aluminum alloy plate superior in press formability is characterized by providing an alkaline soluble type of lubrication coating with a film thickness of 0.5-10 μm on its both sides or one side, which mainly consists of a polyurethane composition (A), of which the hydrophilic group is a carboxyl group or a sulfonate group with an acid value in the range of 30-180 and a neutralizer of the hydrophilic group is sodium hydroxide or potassium hydroxide, and a lubrication functionalization agent (B) of 1-30 weight % against the polyurethane composition; along with prescribing an alloy composition and a value of difference (TS-YS) between a tensile strength (TS) before press forming and 0.2% yield strength (YS). The alkaline soluble type of lubrication coating preferably further includes silica particles (C) of 1-30 weight % against the polyurethane composition, as a main component.

摘要： The present invention provides a high corrosion resistance hot dip galvannealed steel material comprised of a Zn-based hot dip plated steel material achieving both a higher corrosion resistance of the plated layer itself by the added elements and sacrificial protection of iron metal by the plated layer or workability free of degradation caused of formation of intermetallic compounds by added elements, that is, a high corrosion resistance hot dip Zn plated steel material characterized in that an alloy plated layer containing Zn: 35 mass% or more, preferably 40 mass% or more, contains a non-equilibrium phase having a heat capacity by differential scanning calorimetry of 1 J/g or more. Furthermore, 5% or more, preferably 50% or more in terms of vol% is an amorphous phase. The alloy layer may contain, by mass%, Mg: 1 to 60% and Al: 0.07 to 59%, may further contain one or more elements selected from Cr, Mn, Fe, Co, Ni, and Cu in a total of 0.1 to 10%, and may in addition contain one or more elements of 0.1 to 10% of La, 0.1 to 10% of Ce, 0.1 to 10% of Ca, 0.1 to 10% of Sn, 0.005 to 2% of P, and 0.02 to 7% of Si.
