| Abstract Scope |
Cyclic bending under tension (CBT) is a cold working process that increases room temperature Elongation to Failure (ETF) beyond what can be accomplished by simple tension (ST) in a variety of sheet metals. The incremental forming approach delays strain localization, potentially facilitating room temperature forming in metals that would normally be formed at higher temperatures. However, retained ductility has been reported to be low in other metals after even small amounts of CBT forming, reducing the potential for a 2-step forming process and resulting in a brittle final product. Initial tests on Ti-6Al-4V sheet indicate that, surprisingly, room temperature ductility is actually increased after medium levels of CBT. Understanding the mechanism behind the unusual behavior will be vital to exploiting novel forming techniques for Ti-6Al-4V, inspired by CBT. |
