I have a couple of cars that need to have their leaf springs re-
arched. One web site mentioned that the process that they use is to
anneal, reform, quench and temper:

I have had leaf packs re-arched in the past and the leaves did not
show any signs of having been heated so I suspect that they only cold
formed them.

I've watched blacksmith shops re-arch leafs cold with a sledge hammer on an
anvil. One guy steadies the leaf on the anvil and the other smacks it
skillfully so as not to cause the leaf end to jolt the one holding it. The
leaf is repositioned after a few wacks.
