Question

1. The activation energy to form interstitial carbon in iron at room temperature is around 0.77 eV, and in vanadium at room temperature, it is slightly less at 0.74 eV. a. Why the difference? Consider the physical differences between atoms of these two elements.

Answer 1

Answer Explanation:

The activation energy to form carbon in iron at room temperature is around 0.77eV, and in vanadium at room temperature it is slightly less at 0.74eV

this is occur due to the following reason that are.

• carbon has the diffusion property and it diffuses in iron and vanadium
• BCC ( body centered cubic) structure of iron
• it has different composition this is the main reason
• different crystal structure of iron
