Draw TTT diagram for 1080 steel and superimposecooling curve for annealing, normalizing, hardening andtempering process and explain how it works using thediagram for each heat treatment processes.Time temperature transformation diagram also known asS-curve, C-curve or isothermal transformation diagram.This is Particularly used in the assessment ofdecomposition of austenite in a heat treatable steel.From the first diagram, we can see the beginning oftransformation, End of transformation and 50%tr
