Description
なお上記のＭｎ、Ｃｒ、Ｚｒ、Ｖ、Ｔｉ、Ｆｅ、Ｚｎ、Ｃｕの含有量範囲は、それぞれ積極的に添加する場合の範囲として示したものであり、いずれも下限値より少ない量を不純物として含有する場合を排除するものではない。特に０．０３％未満のＦｅは、通常のアルミ地金を用いれば不可避的に含有されるのが通常である。 The above content ranges of Mn, Cr, Zr, V, Ti, Fe, Zn , and Cu are each shown as a range in the case of positively adding each of them as an impurity in any amount smaller than the lower limit value. It does not exclude the case of containing. In particular, less than 0.03% of Fe is usually contained unavoidably by using a conventional aluminum base metal.
溶体化処理後には、１００℃／ｍｉｎ以上の冷却速度で、５０〜１５０℃未満の温度域まで冷却（焼入れ）する。ここで、溶体化処理後の冷却速度が１００℃／ｍｉｎ未満では、冷却中にＭｇ２Ｓｉあるいは単体Ｓｉが粒界に多量に析出してしまい、成形性、特にヘム曲げ性が低下すると同時に、焼付硬化性が低下して塗装焼付時の充分な強度向上が望めなくなる。 After the solution treatment, cooling (quenching) is performed to a temperature range of less than 50 to 150 ° C. at a cooling rate of 100 ° C./min or more. Here, if the cooling rate after the solution treatment is less than 100 ° C./min, a large amount of Mg 2 Si or Si single precipitates at grain boundaries during cooling, and at the same time the formability, particularly the heme bendability, decreases. Since the bake hardenability is lowered, sufficient improvement in strength at the time of paint baking can not be expected.
