5. Course Learning Objectives:
Specific objectives of this course are to:

• Provide students in-depth knowledge of the deformation and strengthening mechanisms of metals and alloys.
• Enable students to relate changes in material microstructure and/or phase constitution to changes in mechanical properties.
• Enable students to select appropriate strengthening mechanisms for specific applications.

Desired Outcomes: Students will be able to:

• Relate crystal structure of a material with deformation behavior and inherent mechanical properties.
• Predict the interrelationships between stress, temperature, and principal modes of deformation.
• Predict change in mechanical properties with change in alloy composition, microstructure, or service temperature.
• Select the proper metallic materials based on desired performance / cost constraints.
• Communicate clearly and effectively by presenting both oral and written reports.
• Work effectively as part of a team by conducting laboratory experiments in groups.
