SUMMARY
Quenching decreases the toughness of materials by inducing internal stresses and preventing them from achieving their lowest energy conformations. This process negatively impacts physical properties such as impact resistance, tensile strength, and flexural strength. Tempering, which follows quenching, alleviates these stresses and enhances toughness by allowing the material to undergo a controlled heat treatment that promotes crystallization in thermal equilibrium. Therefore, the sequence of quenching followed by tempering is essential for optimizing material properties.
