Method of making a structural member for use in the automobile industry |
摘要 |
In a method of making a structural member for the automobile industry, a blank of boron steel is pre-formed at ambient temperature into an intermediary part of a configuration which substantially corresponds to an end shape of a finished structural member. The intermediary part is then coated with aluminum or an aluminum alloy and exposed to a temperature above the upper transformation line in the TTT curve. Subsequently, the intermediary part is formed in a mold into the finished structural member while being hardened at the same time.
