Question 7 0.63 pts Book 7, Section 1, Chapter 12A, Worksheet 2, Question 3. Effect of Larger Size of Grains. Ductility, %elongation change = ; Reason = Enter a number below to match the answer options [1,2,3,4] provided in the workbook. Answer Options: Ductility, %elongation change: (1) decreases; introduction of strain in the lattice impedes dislocation motion; (2) increases; lower probability of dislocation interactions; (3) increases; reduced dislocation density results in lower probability of dislocation interactions; (4) decreases; increased dislocation density results in higher probability of dislocation interactions. ee
