After my daughter’s spinning/dizzy/falling routine, I began to see how her experience related to an elastic material in gradually increasing tension. Her final outburst of tears was representative of the ultimate failure of a metal rod, when it finally cracks into two pieces. If only I could predict it with accuracy... Well, with the help of introductory material science, I think I can.
Material scientists who prepare the recipes for these alloys must consider the effects that time spent at various temperatures will have on the atoms of the metal. In the end, the alloy will exhibit many different qualities. Its mechanical properties are mainly defined by its “stress-strain” curve, which the remainder of this article will ponder.
