I know that it's their first time meeting, not nessesarly a team up and more of a conflict but The Avengers was a conflict for alot of it and it wasn't called Iron Man vs Thor vs Hulk vs Captain America.
Because Avengers is the name of the team.
When Batman and Superman team up they are not known by the name World's Finest. It's the name of the comic book.
