Question
Physics Question on mechanical properties of solids
What happen to the elastic property of a substance after annealing (cooling slowly after heating)
A
Increases
B
Decreases
C
Remains constant
D
Become zero
Answer
Decreases
Explanation
Solution
The process of heating a metal or alloy to an appropriate temperature for a certain period of time and then slowly cooling is called annealing. Annealing reswets in the formation of lange crystal grains, which ultimately reduces the elastr property of the material.
