Dear user
We have as you have not specified any specific question so I am answering according to the HOMEWORKLIB RULES and rules.
Answer 3
Option b is correct
Heat treatment
Strain hardening, is the strengthening of a metal or polymer by plastic deformation. This strengthening occurs because of dislocation movements and dislocation generation within the crystal structure of the material.
Heat treatment can be used to remove the effects of strengthening.
SO OPTION B IS CORRECT
THANK YOU
I AM ANSWERING ACCORDING TO THE HOMEWORKLIB RULES PLEASE SORRY BUDDY :(
WISH YOU ALL THE BEST BUDDY ?? PLEASE UPVOTE IT ?
Add Answer to:
3. Some strengthening effects can be reduced by a. Surface polishing b. Heat treatment c. None...
