Softening heat treatment of alloy increases_________________?
Correct answer: C. Ductility
- A. Tensile strength
- B. Proportional limit
- C. Ductility
- D. Hardness
Explanation
Softening heat treatment relieves internal stresses and produces a softer, more ductile alloy. Tensile strength, proportional limit, and hardness generally decrease rather than increase.
