The same alloy is used to fabricate two different components, both of which result in identical mechanical properties. Cold working yields a microstructure with a much higher incidence of symmetrical grain boundaries for Component 1 as compared with that of Component 2. Which item will most likely have a higher resistance to dynamic embrittlement?

While performing cold working over the material in the region of plastic deformation strain hardening or work hardening occurs. This process re-arrange the member at the microstructural level. The metals are preferred to be worked below their recrystallization temperature. The strain hardening increases the strength of the member. The work-hardened materials are capable of tolerating more stress and at a lower strain rate, and it also elevates the elastic region.
