Thermal conductivity, heat transfer film coefficients. Non-steady state conduction; lumped systems. Convection and radiation. Interstitial diffusion, substitutional diffusion, steady-state diffusion (Fick's first law), nonsteady-state diffusion (Fick's second law), solution of diffusion problems (homogenisation and carburization), atomic mobility, high-diffusivity paths. Casting, forging, hot rolling, injection moulding. Nucleation and growth: homogeneous and heterogeneous nucleation, solid/liquid interface, growth of solid in liquid, growth of solid in solid. Solidification: coring; cells and dendrites; eutectics; segregation in ingots. Kinetics of phase transformations: TTT and CCT diagrams Evolution of microstructure/nanostructure: thermomechanical processing of steels and Al/Mg alloys; hardenability, quenching and tempering of steels, alloying elements.
At the successful completion of this unit you will be able to:
- Describe nucleation and growth of new phases in liquid and solid.
- Describe mechanisms of diffusion and application of it in heat treatment.
- Describe the evolution of microstructure during solidification of metals and alloys under both equilibrium and non-equilibrium conditions and the ability to interpret solidification microstructures in common alloy systems and relate them to the material properties.
- Identify the basis for the design of engineering alloys and their microstructures.
- Describe the thermo-mechanical treatment of engineering alloys with particular reference to steels.
- Describe the effects of processing parameters on structure and properties of steels during their heat treatment and the ability to design simple processing schedules for common commercial steels.
