The list of topics for the entry exam to the AGH Doctoral School in discipline Materials Science

Metallurgy

  • Discuss theories of oxidation of metal sulphides.
  • Discuss the role of hydrogen overpotential in the process of iron group metals electrodeposition and the influence of electrolysis parameters on hydrogen overpotential and current efficiency.
  • Discuss the process of copper production in case of a shaft furnace technology and a flash furnace technology.
  • Production of aluminum by electrolysis of molten salts, discuss the influence of the cryolitic number on electrolyte melting temperature and solubility of aluminum oxide.
  • Give a thermodynamic condition for the balance of the chemical reaction. Using the example of Boudouard's reaction, determine the effect of pressure and temperature on the equilibrium of this reaction.

 

Material science

  • Methods of strengthening metals and alloys.
  • What are the mechanisms of plastic deformation - characteristics.
