Solution
The correct option is A Rolling
The explanation for correct option:
A. Rolling
Heat treatment:
- It is a process of heating a substance/metal without letting it reach its melting point/molten state.
- “Heat treatment involves the use of heating normally to extreme temperatures in order to get the desired result such as hardening/softening of a material.”
- It is generally used to make the metal stronger/malleable or more ductile and resistant to abrasion.
Rolling is not considered a heat-treatment process.
The explanation for incorrect options:
The techniques such as annealing, tempering, normalizing, quenching, etc are heat treatment techniques. Thus, options B, C, and D are incorrect.
Hence, the correct option is A i.e. Rolling.
