Answer is:
Process annealing
Answer is:
All of these
Explanation:
When the steel is normalized, its Yield point increases, Ductility decreases and Ultimate tensile strength increases
Answer is:
Normalizing
Explanation:
Normalizing is a slow cooling process so after casting job is left in air to cool it.
While annealing is very slow cooling process in which job is left in furnace switching it off to relieve residual stresses coming from cold work.
