Two previously undeformed specimens (i. e. 0% cold work) of the same metal are to be plastically deformed by reducing their cross-sectional areas. One has a circular cross-section, and the other is rectangular; assume the shapes do not change during the process. Their original and deformed dimensions are as follows:
Circular (diameter, mm) Rectangular (mm)
Original dimensions 18.0 20 × 50
Deformed dimensions 15.9 13.7 × 55.1
Which of these specimens will be the hardest after plastic deformation, and why?
