Implication

This study investigates mechanical performance improvement through austenitizing and tempering in AISI 4140 and 4340, indicating enhanced impact toughness.

Key Points

Heat treatment significantly improved the mechanical performance of AISI 4140 and AISI 4340 steels.
Austenitizing and tempering processes enhanced impact toughness while altering hardness and tensile strength.
Microstructural assessments using optical and scanning electron microscopy revealed formation of bainite and tempered martensite.
Isothermal retention at higher temperatures produced untempered martensite, indicating potential for specialized applications.
