Question:

Creep of mild steel at elevated temperature involves

Show Hint

Creep in materials, especially metals like steel, occurs when the material is subjected to a constant load at elevated temperatures, leading to plastic deformation over time.

The Correct Option is C

Solution and Explanation

Creep is the slow, time-dependent deformation of a material under a constant load, typically occurring at elevated temperatures. For mild steel, at elevated temperatures, the material undergoes plastic deformation under a constant load over time. Hence, creep is associated with plastic deformation under constant load.
Thus, the correct answer is (C).
