Question

Tempering is a heat treatment process by which

• A. Hardness is Reduced and Toughness is Improved
• B. Hardness is Improved and Toughness is Reduced
• C. Toughness is Reduced and Hardness is Improved
• D. Toughness is Improved and Hardness is Improved

Hint:

Tempering is essential for reducing the brittleness of hardened steel while improving its toughness typically done after hardening

Answer 1

The Correct Option is A

Tempering is a heat treatment where a material, typically steel, is heated below its critical point and then cooled. This process reduces brittleness, increases toughness, and decreases hardness. Consequently, tempering is commonly used to balance these properties, improving the material's ability to absorb energy without fracturing.
