Texts: An iron sample is deformed to a shear strain of 0.3, with resulting dislocation density of 10^10 cm^-2. What is the average distance each dislocation moved during this deformation? If the strain rate during this deformation was 10^-2 s^-1, what was the average dislocation velocity? In Fe, the atomic radius is 0.124 and the shear modulus is 70 GPa.
