Students attending ASM Materials Education Foundation camps are taught and engage in a variety of materials science and engineering concepts—including failure analysis. As part of the weeklong camp, high school students perform failure analysis on actual fractured components and present their results at the end of the camp. In 2019, the students of one group were tasked with determining the failure of a stick end from a commercial pasta drying system. This presentation will detail their results, obtained by performing optical and electron microscopy, as well as chemical and mechanical testing. Their analysis found that poor manufacturing practices and a lack of maintenance led to continued failure of these parts in service. This failure analysis as well as other failure projects performed at the Materials Camp will be highlighted.
