Metal science and metal protection from corrosion laboratory № 4

  • Laboratory traditionally works to improve operational properties of alloyed special purpose construction steels and casts and to create new original compositions of alloys. Works are performed by alloying and thermo mechanical processing optimization, improving macro and microstructural and physical-mechanical properties. Laboratory supervises research of technological processes of metals melting-molding and pressure processing by using metallographic and physical-chemical methods. Several special steel compositions were created in the laboratory. Research was performed on thermal fatigue of construction steels, to reveal the influence of dopant elements on gaseous erosion and to create composition of alloys that will have increased endurance while operating under harsh conditions.
  • Examination of metals and metal ware is performed in the laboratory in order to determine compliance with the standards and real damage causes of details. Expertise works are performed on ferrous as well as non-ferrous metals.
  • Ancient bronze (with arsenic, tin and other) artifacts were researched. Their making and molding technologies were estimated.
  • Structural research of cross-grained (Damascus steel) steel was performed. The peculiarities of obtaining such steels were studied. The optimum amount carbon of steel’s major alloying elements was estimated. Low-temperature regime of forging was developed, which lead to the obtaining of granular perlite, increased plasticity and durability and respectively cutting capacity of the work piece.

 

 

It is possible to manufacture at the institute a small number of souvenir knives from cross-grained steel

 

  • Historical and technological analysis of iron and steel making process technology is being done in ancient primitive shaft type furnace.
