Understanding the structure and properties of metals helps engineers determine their usefulness for a specific application. For example, knowing the ability of a metal or material to react to variable forces (loads) is of particular importance. Mechanical engineers calculate these forces to establish the service that can be expected and material scientists experiment to determine how metals deform (elongate, compress, and twist) or break as a function of applied load, time, temperature, and other conditions.
This course explains the basic structure and properties of metals, which is critically important when identifying the most appropriate metal to use for each application. It also discusses how metals are affected by various processes, imperfections, or defects.
Learning Objectives
Upon completion of this course, participants will be able to:
- Describe the nature and characteristics of five types of bonding that occur in materials.
- Identify the three most common crystalline structures: body-centered cubic, face-centered cubic, and hexagonal close-packed structures.
- Describe common characteristics of alloys.
- Identify the three types of microscopic imperfections found in crystalline structures.
- Distinguish among tensile, compressive, and shear stresses.
- Differentiate between elastic strain and plastic deformation.
- Explain Hooke’s law and Young’s modulus as they relate to stress.
- Interpret a stress-strain curve, including the application of Hooke’s law and the elastic and plastic regions.
- Identify important physical properties of metals, including strength, ultimate tensile strength, yield strength, ductility, malleability, toughness, and hardness.
- Explain the effects of temperature changes, irradiation, and cold working on ductility.
- Describe how heat treatment affects the properties of steel and carbon steel.
- Explain why galvanic corrosion is a concern in design and material selection.
- Identify the two required conditions for hydrogen embrittlement and explain its formation process.
Certificate of Completion
You will be able to immediately print a certificate of completion after passing a multiple-choice quiz consisting of 40 questions. PDH credits are not awarded until the course is completed and quiz is passed.
