| The goal | Mastering the principles of alloying on the relationship between the chemical composition, structure and properties, as well as the skills necessary to direct the actions of melting, refining, casting and hardening alloy steels, stainless steels and special alloys. | |||
| The outcome | The course provides the necessary knowledge to understand the processes of alloying of special steels and alloys. Instructs the student to the classification, standardization and design of specific special steels and alloys, and the properties that are required in exploitation | |||
| Contents | ||||
| Contents of lectures | Principles of alloying. The influence of alloying elements, micro-alloying additions, gas and impurities on the properties of special steels and special alloys. Procedures smelting special steel and alloys. The theoretical basis derived from phase equilibria in the system Fe-Cr-CO. Two methods of making stainless steel with ultra-low C-content Conversion AOD process. Oxidation in a vacuum, VOD process. Smelting and refining of stainless steels and special alloys in an induction furnace in air and in vacuum, the plasma arc furnaces and kilns in the electron beam. Combined melting in a vacuum induction furnace with refinement in a cascade of electron-beam furnace. Specifics of the continuous casting of special steel. Directional solidification of special alloys. Features refining and hardening superalloys based on nickel and cobalt as well as fire-resistant alloys based on chromium, molybdenum and niobium. | |||
