EN380: Naval Material Science and Engineering

Catalog Description

EN380: Naval Material Science and Engineering (3-0-3)

This course addresses the optimal use of materials in ocean systems with emphasis on corrosion prevention, fracture mechanics, and basic materials science.

Textbook

  • Various supplemental materials, including handouts/packets on corrosion, basic material science, metallurgy, heat treatment, and materials applications.

Goals

  1. Demonstrate a basic understanding of mechanical properties of materials commonly used in marine applications, including strength, toughness, and hardness, as well as failure mechanisms of fracture, fatigue and creep.
  2. Demonstrate a basic understanding of metals and metal alloys commonly used in marine applications, including low carbon steels, alloy steels, tool steels, stainless steels, aluminum alloys, copper alloys, nickel alloys, and titanium alloys, including composition, physical and mechanical properties, fabrication, uses, and nomenclature.
  3. Demonstrate a basic understanding of phase transformation and heat treatment of metals and metal alloys, including basic metallurgical changes and effects on physical and mechanical properties.
  4. Demonstrate a basic understanding of corrosion in marine applications, including the nature of corrosion, corrosion prediction and measurement techniques, and corrosion control techniques.
  5. Demonstrate a basic understanding of composites commonly used in marine applications, including fiber-reinforced polymer (FRP) composites, concrete, and wood, including composition, physical and mechanical properties, fabrication, uses, and nomenclature.
