Q1. What is heat treatment process?
Ans. 
Heat treatment process involves heating and cooling metals to alter their physical and mechanical properties.
• Heating metal to a specific temperature

• Holding it at that temperature for a certain period of time

• Cooling it at a controlled rate

• Types include annealing, quenching, tempering, and normalizing

Q2. What are different types of heat treatment process?
Ans. 
Different types of heat treatment processes include annealing, tempering, quenching, and case hardening.
• Annealing: Heating metal to a specific temperature and then slowly cooling it to relieve internal stresses and increase ductility.

• Tempering: Reheating quenched metal to a specific temperature to improve toughness and reduce brittleness.

• Quenching: Rapidly cooling heated metal to increase hardness by forming a martensi...read more

Q3. What is quenching?
Ans. 
Quenching is a heat treatment process used to harden and strengthen metal by rapidly cooling it after heating.
• Quenching involves heating a metal to a specific temperature and then rapidly cooling it in a quenching medium such as water, oil, or air.

• The rapid cooling causes the metal to undergo a phase transformation, resulting in increased hardness and strength.

• Different quenching mediums are used depending on the type ...read more
