Answer» The correct option is (c) annealing Explanation: Annealing is the process of heating the STEEL to a sufficiently high temperature to relieve local internal stresses. It does not create a general softening of the product but only locally relieves STRAINS and stresses locked up within the material. Annealing goes through three phases: recovery, recrystallization, and GRAIN growth. The temperature required to anneal a particular steel depends on the type of annealing to be achieved and the alloying CONSTITUENTS.
