Be-Cu precipitation hardening experiment

The following is a laboratory experiment designed to further a student's understanding of materials science. The student performing this experiment should have a knowledge of binary phase diagrams. The objectives of this experiment are as follows: (1) to give the student a hands-on approach to changing materials properties through heat treatment of a specimen; (2) to quantify the amount of strengthening obtained in the specimen; and (3) to encourage the student to speculate about the structural changes that have occurred in the material to cause the changes in strength.
