Graphitization wiki

WebGraphitization is a form of material degradation occurring when the microstructure of some carbon and low alloy steels breaks down after long exposure to elevated temperatures (825 - 1300 F), causing the metal to weaken and be susceptible to cracking failures. WebGraphite (/ ˈ ɡ r æ f aɪ t /) is a crystalline form of the element carbon.It consists of stacked layers of graphene.Graphite occurs naturally and is the most stable form of carbon under standard conditions.Synthetic and …
