Author Profile

Summary

In this exercise, students match microstructures to the deformation mechanisms by which they form; compare pairs of photomicrographs chosen to highlight key differences between some common microstructures; and complete a self-quiz in which they identify microstructures and infer deformation mechanisms from photomicrographs.

Learning Goals

After successfully completing this exercise, students will be able to

Context for Use

We use this as a homework exercise to give students practice in both identifying microstructures and associating them with the deformation mechanisms by which they form.
