Larson Miller parameters.
If you are talking about foil that is a few thousandths of an inch thick then you can anneal in a couple of seconds.
Otherwise the outer surface gets too hot (grain growth or incipient melting) before the inside sees enough time at temp to anneal.
What alloy?

Anneal at the top end of the range 700-750F. Above this grain growth will be an issue.
Just be warned that rapidly heating to this temp may cause more distortion.
As an ides 15sec at 750F is roughly equivalent to 9min at 650F.
