Work Hardening and Annealing of Copper

This four-page guide from Edmonds Community College provides a laboratory activity demonstrating the process of work hardening and the annealing of copper. Students observe the hardening of metal by deformation, the effects of work hardening in metals, and the effects of processing on materials properties. This activity takes around sixty minutes, and can be adjusted for fourth grade through college classrooms. This guide includes the following sections: Objectives, MatEd Core Competencies Addressed, Equipment and Supplies Needed, Instructor Information, Experimental Process, and Evaluation.
