Prepare a report of the type set forth in the course syllabus. The report is to include the following data and analysis:
1. On a single graph, plot "Hardness" as the ordinate versus "Aging Time" as the abscissa for each aging temperature.
2. Discuss the effect of aging time and temperature on the effect of material hardness.
See the section on Precipitation Hardening in Reference [1] below.
3. Compare the hardness of Specimens 1 through 7 and elaborate on your observations.
