1.	Neutralization of preexisting defects in the material can lower the chances of fatigue failure.(a) True(b) FalseThis question was addressed to me by my college director while I was bunking the class.Question is from Metallurgical Aspects in division Mechanical Working of Metals of Casting-Forming-Welding II
Answer» Correct choice is (a) True Best explanation: The fatigue life of material can be IMPROVED by various treatments which generally includes GRINDING, shot peening, SPOT heating, hammer peening, heat TREATMENT etc. And also by considering strategies like neutralization of preexisting defects and reducing local stress concentration, fatigue life of material can be improved.
