The element vas not vibranuim it was badassium:

The New Element that was originally theorized by Howard Stark after his research of Tesseract. He believed it could be source of limitless energy, but wasn't capable to create the element. Tony Stark's chest-build Arc Reactor required heavy element, such as Palladium, in order to work. However, Palladium released toxins in Arc Reactor, slowly poisoning Tony. With need to gain better energy source, Stark found his father's blueprints, built small particle accelerator and eventually created New Element. This element appeared only shortly, being solid and constantly glowing material.

The New Element was incorrectly called "vibranium" in a novelization. Vibranium was later introduced in the 2011 film Captain America: The First Avenger.

Later in comic book was revealed that Tony wanted to patent his new element as "Badassium", but ran into several legal issues.
