Abstract
Description
グローバルな省エネルギー、排出量削減、環境に優しい経済に対する差し迫った要望に対して、自動車産業は軽量化の方向で開発を進めているが、自動車の軽量性は安全を犠牲にするものではない。その反対に、自動車に対する衝突安全要件はますます高くなってきている。今日、自動車産業において、車両用の高強度、超高強度鋼材がそれらの高い強度と軽量性とにより益々注目を集めるものとなってきている。高強度のために、冷間スタンプ成形法が採用されるが、それによって、成形特性が低減し、大きなスタンプ成形力が必要とされ、亀裂が容易に生じる。更に、成形後、パーツのリバウンドが大きく、それによって、その形状と寸法精度とを補償することがほとんどできなくなる。
以下、実施例を例にとって本発明をより詳細に説明する。下記の実施例又は実験データは本発明を例示するためのものであって、当業者は本発明がこれらの実施例又は実験データに限定されるものではないことを認識すべきである。
