Cold working of iron leads to increase in dislocation density from 10^10 to 10^15 m^-2. The associated stored energy (in MJ. m^-3, rounded off to one decimal place) is _________. Given: Shear modulus of iron = 82 GPa, Burger’s vector, b =a0/2[111]. a0=0.2856 nm.
Ans = 2.5
Ans = 2.5
See lessHello bk, Energy of dislocation is 1/2 (Gb*b). You can find the solution on my channel at 9:00 https://www.youtube.com/watch?v=RMvFvC-_n_s&list=PLFS_xICJ_zVPwqvTZ6QToink9EOBilj-x&index=6
