Which of the following will be rendered useless for prevention of creep?

(a) Coarse-grained material

(b) Strain hardening

(c) Precipitation hardening

(d) Quenching

This question was addressed to me by my college professor while I was bunking the class.

Origin of the question is Mechanisms of Creep & Creep Resistant Materials in chapter Plastic Deformation and Creep in Crystalline Materials, Elastic, Anelastic and Viscoelastic Behaviour of Engineering Material & Metallurgy

Correct option is (d) Quenching

Easy explanation: Creep fracture can be prevented by using coarse-grained materials and treatment by strain hardening a precipitation hardening. The material must be free from residual stresses and can also be heat treated.
