Physical Metallurgy Structures


Course Description

An interpretative study incorporating phase equilibria, diffusion, nucleation and growth, solid state transformation, strengthening mechanisms; effects of alloying, deformation, precipitation, recrystallization and grain growth on microstructure. Microstructural interpretation of ferrous and non-ferrous metal is emphasized.

Prerequisites

(A requirement that must be completed before taking this course.)

Course Competencies

Upon successful completion of the course, the student should be able to:

  • Summarize the basic forms of metallurgical transformations as shown on phase diagrams.
  • Predict phases present in a structure using the lever rule.
  • Explain the basic heat treating processes including annealing, normalizing, hardening and stress relieving processes.
  • Produce both equilibrium and non-equilibrium structures in steel.
  • Compare equilibrium and non-equilibrium structures in steel.
  • Interpret the thermal based decomposition of pearlite to spheroidite.
  • Interpret the influence of alloying on the microstructure of carbon and alloy steels, stainless steel, cast iron and aluminum alloys.
  • Depict the behavior of time, temperature and transformation on the resulting microstructures identified on an isothermal transformation diagram.
  • Interpret microstructural defects including decarburization, origins of cracking, and the presence of retained austenite.
  • Explain the differences between surface and case hardening.
  • Relate the methods used to measure hardenability as a method for establishing heat treating parameters and material selection criteria.
  • Improve proficiency in metallurgical laboratory practices and microstructural interpretation of the morphology of ferrite, martensite, austenite and bainite.
