Course Description

This course introduces the properties of various metals, production methods, and the identification of ferrous and non-ferrous metals. Topics include heat treatment safety, metallurgy principles, and the heat treatment of metals. This course also provides instruction in the safe setup, operations, and maintenance of surface grinders.

Metallurgy

  • Define all the terms that describe the physical properties of metals.
  • Describe non-ferrous metal, and the purification processes for the common non-ferrous metals used in industry.
  • Outline the variation found in steel alloys, and how each affects the physical properties, cost, and machinability of the steel.
  • Explain crystal structure of metals.
  • Explain the numbering system used by the agencies that set standards for production of metal alloys.
  • Discuss metallurgical properties of ferrous and non-ferrous metals.
  • Discuss the advantages and uses of coatings or plating on metals.

Heat Treatment

  • Define the terms used for each type of heat treatment (example: hardening, anneal, temper, draw, etc.).
  • Explain upper and lower critical temperature, austinizing temperature, phase change temperature, and tempering limits on temperature.
  • List the quenching solutions by their rank in severity and rate of agitation.
  • Explain how the severity of quenching is compared to that of still water.
  • Explain how severity of the quenching process affects the physical properties of the meta..
  • Determine the hardness of metals with a Rockwell hardness tester.
  • Explain how pendulum testing, charpy test, and tensile testers relate to the properties of metals.
  • Discuss the affect of heat on cutting tools and the cutting process.
