Course Objective

1.Explain principles of heat treatment procedures for metals and alloys, explain the effect of heat treatment parameters on microstructure and on material properties. 2.Perform a heat treatment procedure to obtain desired properties. 3.Do team work on a heat treatment process and write up technical reports.

Course Content

Property changes due to heat treatment. Iron-carbon system. Austenitizing transformation of austenite, I-T and C-T diagrams, annealing, normalizing, hardening, critical cooling rate. Actual cooling rate, quenching media, size and mass effect. Hardenability and applications of hardenability data. Tempering. Secondary hardening, temper embrittlement, austempering. Case hardening. Residual stresses, martempering.

Learning Outcomes

Students apply techniques to practice heat treatment of metals and use physical metallurgy and materials characterization knowledge to the specifics of metal heat treating.
