True/False: Water and ice have the same chemical formula, so they are the same phase. True/False: Hardness is proportional to tensile strength. True/False: Recovery is the first stage in the in the removal of the effects of cold working when a cold - worked metal is slowly heated. True/False: True stress is always smaller than the engineering stress. 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 ___.
Solution
7. False
8.True
9. True
10.False
11. True
12. Eutectoid
13. Cold worked metal
14. As cold working increases, ductility decreases, tensile strength increases, yield strength increases.
