5-4 When an FCC material has high stacking fault energy, do you expect widely-spaced or closely-spaced leading and trailing partial dislocations? Do you expect wavy or planar glide? Briefly explain both trends. pts 5-5 Identify the trend between stacking fault energy and work-hardening coefficient, and then use it to predict which is likely to work harden more strongly: pure copper or pure nickel, the latter of which has a stacking fault energy of approximately

. Hint: high work hardening coefficient means the dislocation is hard to move and crossslip.
