- Further information
- This is an example of a quenched and tempered steel. The steel is initially quenched from the austenite phase field to form hard and brittle martensite. Subsequently the steel is reheated to allow diffusion of the interstitially trapped carbon and hence reduction of the lattice strain. This results in a softer and tougher steel.
