MS3002 Materials Science and Engineering II

This is the second course of an introductory two-course sequence of the MAE Materials track. This course will continue to emphasize the basic principle of processing-structure-property relationships in materials and relate this to engineering materials of naval relevance. Students will practice the characterization techniques, like hardness testing, introduced in MS3002. Corrosion of engineering materials will be introduced with a focus on electrochemical basics, interpretation of Pourbaix diagrams, and how corrosion leads to failure. Welding (from 3001) and corrosion will be linked to performance and failure of materials in service. Examples pertinent to Naval, Aero and Combat Systems Science are emphasized. Additional topics include mechanical properties, fracture, fatigue, and failure analysis.

Prerequisite

MS3001 is the first course in this two course sequence. Students will need to know about basic structure-property relationships taught in MS3001 to succeed in MS3002, the second course of the sequence.

Course Learning Outcomes

• Be able to explain the different types of corrosion and how each may ultimately lead to failure in materials.

• Interpret a Pourbaix diagram and estimate whether corrosion will occur in a metal placed in a particular environment.
• Estimate the polarization behavior of an alloy using an Evans diagram. Determine whether an alloy will passivate given chemical and polarization data.
• Understand basic fracture mechanics and explain the models that pertain to brittle and ductile materials.
• Be able to discuss fatigue and fatigue fracture in engineering materials.
• Explain how welding or corrosion can lead to failures like hydrogen embrittlement or stress corrosion cracking.
• Identify alternative materials to resolve a problem found in naval assets.
