__________ is a form of damage found mostly in older vintage carbon steels and C-0.5 Mo low alloy steels under the combined effects of deformation and aging at an intermediate temperature.

Question

Quizplus · Accepted Answer

Strain aging is a phenomenon in which additional strength and hardness develop in steel due to the interaction between dislocations and solute atoms during plastic deformation at an intermediate temperature, typically between 200°C and 400°C. This can lead to embrittlement and cracking of the material, especially in older vintage carbon steels and C-0.5 Mo low alloy steels. Spheroidization is the process of forming spheroidal carbides in steel, while thermal fatigue refers to cracking due to cyclic heating and cooling.
