Course Description

This is an introductory course emphasizing the understanding of the structure and properties of the materials, and the design and selection of materials for engineering applications. Studies include analysis of ferrous and non-ferrous metals, ceramics, polymers, composites and semiconductors. Emphasis is on micro and macro structure, relationship between the structure and properties of materials, and effect of heat, stress, imperfections and chemical environments on material structure, properties and performance. Topics also include mechanical, thermal, electrical (including semiconductors), magnetic and optical properties and also corrosion and degradation of materials. PREREQUISITE: CHEM A180 and PHYS A185 or PHYS A185H. Transfer Credit: CSU; UC. C-ID: ENGR 140.C-ID: ENGR 140.

Course Level Student Learning Outcome(s)

1. Explain the internal structure (macro- and micro-) of materials and its effect on the material properties.
2. Explain the methods (intentional or unintentional) to modify the properties of the material by altering its structure by mechanical mechanisms, and altering the composition (i.e. chemically), and by thermal means.
3. Recommend a suitable material or materials for specific applications and to meet the design criteria based upon the data of the properties, processing and the performance of materials of all classes.

Course Objectives

• 1. Describe the primary and secondary bonding, and crystal structure for metals, determine the crystallographic points, directions and planes, determine miller indices, and explain the material microscopic visualization techniques and determine the grain size.
• 2. Explain types of imperfections in materials, their effect on properties of materials, and how to alter the properties using defects. Also determine the solid state diffusion and it effects on the properties, especially surface properties on the materials.
• 3. Explain the stress-strain behavior and determine the mechanical properties of the different types of materials, including changes in structure. Determine the effect of temperature and strengthening mechanisms. Explain different failure modes for various types of materials under different loading conditions and their role in selection and performance of materials.
• 4. Use the equilibrium and non-equilibrium phase diagrams to control the microstructure and the properties of materials and design the materials using variation in composition and thermal processes.
• 5. Select and recommend material/materials for specific use, utilizing the collection of data on mechanical and other properties. Selection of metallic and non-metallic materials based on their physical properties and typical applications.
• 6. Explain and select the joining, forming, fabrication and machining and/or other processes to manufacture the components. Use metallic, ceramic, polymeric and composite materials. Explain the processes to design the particle- and fiber-reinforced composite materials.
• 7. Identify ceramic structures and types and processing of ceramic materials and identify polymer structure, and characteristics and processing of polymeric materials.
• 8. Identify the electrical properties of materials and explain the process of conduction, semiconductivity and dielectric behavior. Explain the mechanisms of thermal, magnetic and optical properties of materials.
• 9. Explain various corrosion and degradation processes and their effects on the properties of materials.
