Cold Working and Intermediate Annealing
Assertion (A): To obtain large deformations by cold working intermediate annealing is not required.
Reason (R): Cold working is performed below the recrystallisation temperature of the work material.
Explanation:
Cold working is a process in which metal is deformed below its recrystallisation temperature. The process is also known as cold forming or cold heading. It is a method of strengthening metals by plastic deformation. Cold working can produce large deformations in the metal, which are useful in various applications.
Intermediate annealing is a process that involves heating the metal to a certain temperature and then cooling it slowly. The process relieves internal stresses in the metal and makes it more ductile. It is usually done between cold working operations to prevent cracking or tearing of the metal.
Assertion (A) states that intermediate annealing is not required to obtain large deformations by cold working. This statement is true because cold working can produce large deformations without the need for intermediate annealing. Cold working can produce deformations of up to 90% in some materials.
Reason (R) states that cold working is performed below the recrystallisation temperature of the work material. This statement is also true. Cold working is performed at room temperature or below the recrystallisation temperature of the metal. The process of cold working below the recrystallisation temperature makes the metal stronger and more resistant to deformation.
Conclusion:
Therefore, both Assertion (A) and Reason (R) are true. However, Reason (R) is not the correct explanation of Assertion (A). The correct explanation of Assertion (A) is that cold working can produce large deformations without the need for intermediate annealing.
