Question: A bcc crystal with lattice parameter a0 = 3.0 and containing interstitial nitrogen atoms is strained along the [001] direction by putting a weight on

A bcc crystal with lattice parameter a0 = 3.0 and containing interstitial nitrogen atoms is strained along the [001] direction by putting a weight on it. Immediately after the weight is added, a strain of 1.0010-5 is observed. The strain is found to increase with time. After 1 hour the strain reaches a value of 1.1910-5 and after a very long time reaches 1.3110-5. What is the value of the diffusion coefficient for the impurity in the crystal?
