用于增强铆接能力的方法和系统
摘要：
公开了用于增强铆接能力的方法和系统。公开了一种接合的板材堆以及用于形成堆的方法和系统。堆可包括钢板和另一个板。钢板可包括主体部分以及一个或更多个紧固区域，主体部分具有第一抗拉强度，所述一个或更多个紧固区域具有小于第一抗拉强度的第二抗拉强度以及包括回火马氏体的微观结构。紧固件可延伸穿过每个紧固区域而将钢板接合到另一个板。该方法可包括对钢板的一个或更多个区域进行热处理，以形成具有小于钢板的主体抗拉强度的抗拉强度以及包括回火马氏体的微观结构的一个或更多个紧固区域。然后，可将紧固件插入到所述一个或更多个紧固区域中以将钢板接合到另一个板。
摘要（英）：

The invention discloses a method and system for enhancing rivetability. A joined sheet stack and a method and system for forming the stack are disclosed. The stack may include a steel sheet and a second sheet. The steel sheet may include a bulk portion having a first tensile strength and one or more fastener regions having a second tensile strength that is lower than the first tensile strength and a microstructure that includes tempered martensite. A fastener may extend through each fastener region joining the steel sheet to the second sheet. The method may include heat treating one or more regions of a steel sheet to form one or more fastener regions having a tensile strength that is lower than a bulk tensile strength of the steel sheet and a microstructure that includes tempered martensite. A fastener may then be inserted into the one or more fastener regions to join the steel sheet to a second sheet.
