I know people say wikipedia is unreliable, but I doubt someone would screw about with something as subtle as Vanadium, so I guess that counts as a reliable source. However, just because somethings makes no reference to something doesn't necessarily mean it doesn't happen. It might still happen elsewhere.

Honestly, the whole debate over the reliability of Wikipedia is well and truly done, as it's one of the few large databases of information on the internet freely accessible to everyone. While textbooks are the most reliable source, it would be difficult for some of us to gain access to the same textbooks, and for most of us it would take too long to acquire these books to respond in a timely manner.

Vanadium is also not quite as subtle as you think, what with it being used in high-speed steels that are quite superior to standard steel produced without alloying.
