    Quenching--Heat to a temperature within the austenite phase region and allow the specimen to fully austenitize, then quench to room temperature in oil or water. The final microstructure is martensite. Tempering--Heat a quenched (martensitic) specimen, to a temperature between 450 and 650 C, for the time necessary to achieve the desired hardness.
