Abstract

A hybrid component for lightweight, structural uses, including a steel member formed of a high strength steel; and a cast coupling member cast on a portion of the steel member by casting-in-place a semi-solid aluminum about the portion of the steel member, thereby positively and rigidly securing the coupling member to the steel member. A method of forming a hybrid component for lightweight, structural uses, including: forming a steel member formed of a high strength steel into a predetermined configuration; and casting a coupling member on a portion of the steel member by casting-in-place a semi-solid aluminum about the portion of the steel member, thereby positively and rigidly securing the coupling member to the steel member.
