It seems to me that twisting the wire in that way over stresses (particularly) the outer fibres past the elastic limit which is another way of saying they have lost their ‘springiness’. There may be some spring left towards the centre of the wire but the ‘dead’ outer fibres will hold it straight. My concern would be that if I bent, say, a propeller hook that under load the hook would start to open out because the wire has lost most of its elasticity. I confess I am not a metallurgist nor a stress man just an old mechanical designer who has been retired over a quarter of a century!

I have a music shop just a couple miles from my house, and they stock guitar strings in every size from .007 to .017. Finding a way to straighten it is nice because now I can get whatever size I need quick and cheap from a local store. I think each string is $2-3, and is maybe 3 feet long.

I've had great success using the technique in this video. As Mike mentioned you can see visible twisting in the wire, but it doesn't seem to have any negative effects. I've done this to a bunch of .013" guitar string wire, and it came out absolutely dead straight.

I mentioned that in the article. Didn't work for me, ended up with a bunch of wire I had to toss out.
Jake Palmer pointed me to a youtube video that shows how to use a drill. I used this on some 0.022" and got some visible twisting in the wire, but it was straight. I haven't had the time to try it on 0.013" or smaller yet.
