Temper brittleness of a material can be fairly detected by the ________________ test ?
Correct answer: B. Notched bar impact
- A. Fatigue
- B. Notched bar impact
- C. Tensile
- D. Hardness
Explanation
Temper brittleness reduces toughness, especially in a notched specimen, so it is revealed effectively by a notched-bar impact test. Tensile and hardness tests may show little change even when impact toughness has deteriorated.
