A sample of metal is subjected to a force which increases to a maximum value and then decreases back to zero. A force-extension graph for the sample is shown. [Figure 19.1] When the sample contracts it follows the same force-extension curve as when it was being stretched. What is the behaviour of the metal between X and Y?
