Question

True/False: Recovery is the first stage in the in the removal of the effects of cold working when a cola-worked metal is slowly healed. True/False: True stress is always smaller than the engineering stress. True/False: Impurities tend to concentrate at dislocations. Short answer. A solid phase transforms into two other solid phases upon cooling, and the reverse reaction occurs upon heating. It is called a reaction. Short answer: The temperature at which recrystallization reaches completion in _______ is called recrystallization temperature. Short answer: As cold work is increased, ductility _____, tensile strength ______, yield strength______.

Explanation / Answer

QUESTION 9

The process of heating a cold worked metal is called annealing. The stages of annealing are  recovery, recrystallization, and grain growth. Thus the first stage of heating a cold worked metal is recovery. TRUE
