I have dought If I need Austenite phase in my eutectoid steel the process is just heat the steel above A1 temparature..Or should I heat the steel upto it’s melting point and then cool to below perritectic temparature to get Austenite?WHICH PROCESS IS CORRECT ?And how the austenite stable when it’s come to equlibrium with room temparature?
