RAV 4980 steel, known as A-286 in the world, is an iron-nickel-chromium alloy with the addition of molybdenum and titanium and belongs to austenitic stainless steels. This steel is characterized by excellent strength and resistance to corrosion and oxidation up to very high temperatures. Due to its good mechanical properties, it is mainly used in aviation, automobile, and oil industry.
The purpose of the thesis was to investigate the effects of the input deformation parameters on workability and recrystallization. These hot compression tests we carried whereas strain rate and temperature varied. Value of strain was constant for all of the compressed samples. The deformed samples were cut in the axial direction and the observed surface area was prepared for light microscopy. The sample was observed also using scanning electron microscope. The low level of dynamic recrystallization in the compressed samples below 1000 °C was detected.
