Bobby Pins

To show the difference that processing, especially thermal processing, can have on the properties of a material

The influence of thermal treatment on bobby pins will be examined. ◊A bobby pin will be annealed by heating it with a Bunsen burner and then slowly cooled. ◊A bobby pin will be quenched by heating with a Bunsen burner and then quickly cooled by plunging the pin in a cup of cold water. · The control bobby pin, annealed bobby pin, and quenched bobby pin will be subjected to an end flexural loading. ◊This type of loading is also referred to as a cantilevered beam loading. · The deflections of each pin will be compared to determine the influence of thermal treatment on the mechanical properties of the metal.
