Question 4 0.63 pts Book 7, Section 1, Chapter 12A, Worksheet 2, Question 1. Effect of More solid solution element atoms; YS, TS Hardness change = - Reason = Enter a number below to match the answer options [1,2,3,4] provided in the workbook. Answer Options: YS, TS, Hardness change: (1) decreases; reduced dislocation density results in lower probability of dislocation interactions; (2) decreases; higher probability of dislocation interactions; (3) increases; introduction of strain in the lattice impedes dislocation motion; (4) increases; increased dislocation density results in higher probability of dislocation interactions. ee
