Question 7/65
Brittle fracture of a component is closely related to:
Correct Answer: A
API RP 571 on Brittle Fracture notes:
"The primary factor influencing brittle fracture is material toughness, especially at low temperatures."
"Materials with low fracture toughness are susceptible to catastrophic failure when stressed below their ductile-to-brittle transition temperature." Hence, option A is correct.
"The primary factor influencing brittle fracture is material toughness, especially at low temperatures."
"Materials with low fracture toughness are susceptible to catastrophic failure when stressed below their ductile-to-brittle transition temperature." Hence, option A is correct.
