I had to look up "work hardening," but that sure makes sense. I did notice that the cracked line when removed had little or no give, where the new line though visually identical was very slightly flexible at the bends. So apparently it vibrated itself into a hard, brittle state and then didn't need much more vibration to snap at a weak point.
