Physical Metallurgy  3111

Teacher: Prof. Roni Shneck

3^rd year undergraduate, Fall semester

Hours of instruction: 3 lecture hours + 1exercise class hour per week

General prerequisites: students should complete the courses of Introduction to materials engineering and thermodynamics.

Course plan

The course describes the thermodynamic and kinetic aspects of the evolution of microstructure of metals and its effect on the mechanical properties of the metal. The course chapters are arranged according the types of defects that control the process.

1. Perfect lattice: lattice structures, phase diagrams

2. Solidification and casting: equilibrium conditions at a solidification interface, the normal solidification equation, thermal and constitutional supercooling, dendrites, micro and macrosegregation, macrostructure of castings, casting of commercial alloys (chapter 14 [1]).

3. Point defects: diffusion, nucleation and growth, precipitation, spinodal decomposition, the industrial process of precipitation and aging (ch. 16)

4. Linear defects: dislocations and plastic deformation, recovery and annealing (ch. 14).

5. 2D defects: interfaces, boundaries, twin boundaries, stacking faults, static and dynamic recrystallization, Avrahami equation, the effect of different factors on the annealed state (ch. 15)

6. Martensitic transformation: crystallography, morphology, microstructure, thermodynamics and kinetics, shape memory effect, heat treatment of steels (ch. 17-19).    

Assessment:

1. Exam   70- 90%
2. Quiz    20% (not mandatory)
3. Homework  10%

                  100%
