Yes Nobby in fact if you read Walkers notes on Rod Building for the practical angler you will see that it was quite common to heat a ferrule to expand it before fitting it to a whole cane section so it shrunk onto the cane as it cooled. This in turn shrunk the cane, the ferrule was then reheated and removed before finally glueing it in place.

There is a tremendous amount of science involved in heat treating different metals and could be talked about for months so I wont even try to go into it in detail but in layman's terms, brass is softened by heating and cooling it but unlike steel and other ferrous alloys it cannot be hardened by quenching, it can only be hardened by working it, however it does self harden with time and this age hardening can lead to stress failure so it may have been a heat treatment that Allcocks used which set up stresses in the ferrules which makes them in particular fail so frequently.
I have removed a Hardy nickel silver ferrule with a split almost half way along and a chrome ferrule with a circular split almost the full circumference of it so it would seem that it doesn't only affect brass.
