热压成形品、其制造方法和热压成形用薄钢板
摘要：
提供一种通过热压成形法成形薄钢板的热压成形品，其金属组织由如下构成：分别含有马氏体：80～97面积%、残留奥氏体：3～20面积%，余量组织：5面积%以下，由此能够将强度和延伸率的平衡控制在适当的范围内，且为高延展性。
摘要（英）：

A hot press molded article comprising a thin steel sheet formed by hot press molding is provided. The metal structure includes 80-97 area% of martensite and 3-20 area% of retained austenite, with the remaining structure comprising not more than 5 area%, and therefore the balance between strength and stretching can be kept in an appropriate range, and high ductility can be achieved.
