Evaluation of carbon diffusion in heat treatment of H13 tool steel

It is known that the hardness obtained from hardening process is greatly influenced by the available carbon content in steel during quenching [1]. The presence of carbon within the steel . Furnaces used for heat treatment hardening experiments: (a) muffle furnace and (b) vacuum furnace. Once the austenitizing time is

tempered in a laboratory muffle heat treatment furnace at a temperature of 200◦C for 1hour and cooled to room temperature in still air. The results revealed that single quenching eliminated the yield strength, increased the tensile strength and hardness properties but decreased the ductility and notch impact toughness prop-.
