Metallurgy and Materials Science - MET 212

Course Description

This course explores the application of phase diagrams, time-temperature-transformation diagrams, thermal treatments and metallography to predict, control and characterize equilibrium and non-equilibrium structures resulting from thermally activated diffusive and displacive phase transformations.

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:

• Demonstrate practical heat treatment laboratory skills based on standard industry practices.
• Demonstrate heat treatment laboratory citizenship skills (safety consciousness, quality focus, teamwork, ethical behavior).
• Demonstrate laboratory notebook and report writing skills.
• Explain the basic types of metallurgical transformations shown on equilibrium phase diagrams.
• Explain the basic heat treating processes, including annealing, normalizing, hardening and stress relieving.
• Produce equilibrium and non-equilibrium structures in steel.
• Distinguish the transformation paths for equilibrium and non-equilibrium structures.
• Explain why Martensite does not appear on the iron-iron carbide binary equilibrium phase diagram.
• Explore the role of diffusion in nucleation and growth processes.
• Explain the effect of alloying on the microstructures of plain carbon, alloy and specialty steels.
• Explain the effect of alloying on the microstructures of aluminum alloys.
• Explain the interplay of time and temperature on transformations and resulting microstructures of steel and aluminum.
• Explain the differences between surface hardening and case hardening of steel.
• Conduct the Jominy hardenability test.
• Examine precipitation hardening in non-ferrous alloys.
