Million (Billion?) Year Structure Change?


Recommended Posts

Ever since I heard about diamonds being able to turn back into graphite over millions of years, I have wondered if the same happens to steel. Now, diamonds and graphite consist of one element, and steel in its most simple form has both carbon and iron, so I don't know if this would still apply. Unless you get the steel to absolute zero, there will still be some atomic-scale movement. All of the processes in chemistry start with a stress, and a reaction to reduce that stress, so would the stress of martensite/tempered martensite eventually turn back into a crystal structure with less stress? A blade that is left untempered can reduce the stress of martensite formation by cracking, so if it somehow doesn't crack over millions/billions of years, I wonder if it could change crystal structure without heat. Now, I will be long dead before any of this matters, but I thought it would be cool to know.
