Question

The fatigue limit or strength of the material can change with respect to time.

(a) True

(b) False

This question was posed to me in an interview for job.

Question is taken from Metallurgical Aspects topic in section Mechanical Working of Metals of Casting-Forming-Welding II

Answer 1

The correct choice is (b) False

For explanation I would say: In many experiments, it has been concluded that the fatigue limit or strength of the material after a long period of time of a metallic material which does not heat up and which surface is not reacted with any other substance chemically during a test remains constant for almost all the practical conditions or purposes.
