Consider the tensile stress-strain diagrams labeled 1 and 2 in Figure 8 - 20 and answer the following questions. These diagrams are typical of metals. Consider each part as a separate question that has no relationship to previous parts of the question.
(a) Which of the two materials represented by samples 1 and 2 can be cold-rolled to a greater extent? Hoe do you know?
(b) Samples 1 and 2 have the same composition and were processed identically except that one of them was cold worked more than the other. The stress-strain curves were obtained after the samples were cold worked. Which sample has the lower recrystallization temperature: 1 or 2? How do you know?
