Average distance between dislocations

Assignment Help Mechanical Engineering
Reference no: EM13887205

Typical values for the dislocation density in annealed and heavily deformed copper are 107 and 1011 cm-2. (For copper: lattice parameter a = 0.361 nm, E = 110 GPa, υ = 0.30, ρ = 8.96 Mg/m3.)

A. Calculate the average distance between dislocations for both cases. For sim- plicity, assume all of the dislocations are parallel and in a square pattern.

B. Calculate with Equation the energy/length of dislocation line for both cases assuming the dislocations are screws.
