A copper cylindrical specimen (A) with a diameter of 1 cm and length of 10 cm is cold-worked to a diameter of 0.50 cm, and later further reduced to a diameter of 0.16 cm (B) a) Determine the total percent cold work of the 0.16-cm plate b) Assuming that all of the dislocations are parallel to each other and they move only one step on a plane of 45 along the axis of rolled fcc Cu, calculate the number of dislocations needed to produce B from A. (rcu 130 pm) c) Compare the following properties of A and B. (equal to, higher than, lower than or inconclusive) i) Density Modulus of Elasticity ii) iii) Hardness iv) Brittleness Resilience v) vi) Toughness
