Q2. Why annealing we needed?
Ans. 
Annealing is needed to relieve internal stresses, improve ductility, and soften the material for further processing.
• Annealing helps to remove internal stresses in the material, making it more ductile and less prone to cracking.

• It also helps to soften the material, making it easier to shape or machine.

• Annealing can improve the microstructure of the material, leading to better mechanical properties.

• Examples of materials ...read more
