Effect of Rolling and Annealing on Hardness of Brass

This five-page instructor guide from Edmonds Community College provides a lesson plan introducing students to the hardness and strength of brass. This lesson demonstrates the changes in the properties of brass caused by rolling and annealing. Through observing these changes in hardness and microstructure, students learn about the effects of processing variations on material properties. This lesson consists of a PowerPoint presentation and discussion, takes one class period, and was designed for advanced high school and college classrooms. The instructor guide includes the following sections: Student Learning Objectives, MatEd Core Competencies Covered, Equipment and Supplies Needed, Curriculum Overview, Module Procedures, and an Evaluation Packet.
