Question

what is the effect of annealing on elastics of materials​

Answer 1

Annealing is a process by which we heat a given object to make it more workable by increasing its ductility and decreasing its hardness as a result its elasticity decreases. while for hammering the crystal grains break up into smaller units owing to which the elastic property of the material increases.
