Heat-treated 4Kh4N5M4F2 steel with adjustable austenitic transformation during operation was studied. The temperature range (450–500°C) in which the tempering brittleness of this steel was manifested was established. The impact toughness of the samples after different tempering temperatures and after steel hardening from 1100°C was determined and it was shown that after tempering at 475°C the minimum value of the impact toughness at room temperature (15 J cm2 ) was reached. The role of Ni as a Fe1–xNix replacement element was analyzed, and the segregation along the grain boundaries of the Me6C carbide phase in the solid solution, which caused a decrease in the impact toughness and an increase in the steel brittleness, was recorded.
期刊介绍：
Materials Science reports on current research into such problems as cracking, fatigue and fracture, especially in active environments as well as corrosion and anticorrosion protection of structural metallic and polymer materials, and the development of new materials.
