Catalog Course Description
An introductory course in engineering materials. Particular emphasis is given to the correlation of material properties and internal structures; structure of materials; stress- strain curves; temperature effects; phase diagrams; ferrous and non-ferrous alloys; ceramics; polymers; composites; electrical, magnetic, and optical properties; corrosion and failure.
Goals, Topics, and Objectives
Core Course Topics
- Introduction to science of materials
- Describe the concept of process-structure-property relationships.
- List the major classifications of materials.
- Atomic structure and interatomic bonding
- Describe the different types of atomic structures.
- Categorize bonds as ionic, covalent,or metallic.
- Explain how the atomic structure and type of bond determines the properties of a material.
- Structure of Crystalline Solids (metals and ceramics)
- Describe various basic crystal structures.
- Explain how the crystal structure affect the densities.
- Describe crystallographic directions and planes.
- Defects and Imperfections
- Describe different types of defects.
- Identify imperfections such as dislocations and vacancies in metals.
- Demonstrate imperfections effect the properties of the material.
- Diffusion mechanisms
- Describe different types of diffusion.
- List factors that influence diffusion.
- Mechanical Properties
- Apply the modulus of elasticity to graph elastic deformations by incorporating Hooke's Law.
- Create plots of stress vs. strain diagrams from the measurement of the tensile strength of materials.
- Describe elastic and plastic deformations.
- Dislocations, slip, plastic deformation,and creep
- Explain how dislocations and slip relate to deformations and creep.
- Explain recovery, recrystallization and grain growth.
- Fracture and fatigue
- Apply the principles of fracture mechanics to predict materials probability of fatigue and failure.
- Describe fracture concepts (e.g. ductility, brittleness, microstructures).
- Phase Diagrams and phase transformations
- Interpret phase diagrams of binary and multiphase alloys.
- Calculate percentages of alloy material at a specific temperatures.
- Evaluate the different phases and microstructures of ferrous metals from the phase diagrams.
- Interpret transformation diagrams as it applies to carbon steel.
- Manufacturing processes
- Be familiar with common manufacturing processes for metals, ceramics, and polymers; their effects on structure; and their impact on sustainability.
- Thermal processing of metal alloys
- Understand how annealing, normalizing, quenching and precipitation hardening effect the hardness of materials.
- Polymer Structures
- Understand the mechanisms of polymerization.
- Corrosion and degradation of Materials
- Describe the process of degradation of metals and polymers.
