摘要

Automakers are increasingly seeking advanced high strength steels for a variety of applications. Until recently, most of these applications involved hang on body parts that were primarily made via roll forming. The part manufacturing process could tolerate some variability in the strength and ductility of these steels. Also, the weldability of the steel onto itself was not a big concern. Today, there is a growing trend to use such steels in body structure components, made primarily by stamping. Consequently there is a strong need to improve coil shape/flatness, make the steel more formable and weldable, and minimize the mechanical property variation within and between coils. This paper addresses the above issues by taking a fresh look at alloy design and processing. The effects of carbon, manganese, silicon, and aluminum additions and the effects of anneal parameter variations on the mechanical properties of the steel are summarized.
