Dislocation density

  1. Mar 25, 2008 #1
    To provide some perspective on the dimensions of atomic defects in solids, consider a metal specimen that has a dislocation density of 10^4 mm^-2. Suppose that all the dislocations in 1 cm^3 were somehow removed and linked end-to-end. How far (in km) would the chain extend? Now suppose that the density is increased to 10^10mm^-2 by cold working. What would the chain length of dislocations in 1 cm^3 of material?

    Can anyone help me with this question, it has me stumped.

    Perhaps if you can determine the average dislocation length in a metal you can multiply it with the dislocation density, or if they are longer than a cm multiply the dislocation density with 1 cm.
