This course concentrates on two things: i) revealing the microstructure of materials; ii) interpretation of microstructure of commonly used metallic materials. 

Aims:   After taking the course the students are expected to:

  • be familiar with macrostructure and microstructures of commonly used metallic materials,
  • interpret the observed microstructure with the help of known physical principles
  • know the basics of metallographic specimen preparation for examination with optical microscope and with scanning electron microscope
  • know the basics of quantifying the micrographs

 

The main aim of the course is to convey a general appreciation of the metallurgical background (specifically physical principles) to practical heat treatment processing. After taking the course the students are expected to:


  • have a general understanding of modern heat treatment applications of metallic materials
  • describe the time - temperature - transformation (TTT) and continuous cooling transformation (CCT) diagrams and their influence on phase transformations
  • understand the concepts of annealing and hardening treatments plus hardenability
  • predict the mechanical properties and microstructures resulting from various heat treatments
  • Tentative course content:

    ·Austenitization, TTA diagrams

    ·Equilibrium and non-equilibrium cooling, TTT and CCT diagrams

    ·Annealing, normalizing, spheroidizing

    ·Hardening and hardenability, case-hardening, tempering and temper embrittlement

    ·Austempering and martempering

    ·Residual stresses and distortion

    ·Thermo-chemical treatments (carburizing, carbonitriding, nitriding)

    ·Thermomechanical treatments
