I have some 'Flexon' memory metal glasses frames that need adjustment where they rest on the ear. All I know is that this is some kind of Ti alloy that is in the superelastic phase at room temperature. This means that it always wants to return to the original shape once the bending force is removed.
What little information I can find on the web suggest that these can be permanently bent into shape but so far I've had no luck at all. I'm worried that if I just keep increasing the force then it will snap before it permanently bends. Is this likely to happen?
Other information suggests annealing the metal at 400-500 deg Celsius, but that will mean destroying the plastic coating where it wraps around the ear.
