“…Близким по сути своей явле-нием может быть образование в исходно парамагнитных твердых растворах ферромагнитных кластеров на основе локальных неоднородностей состава. Такие неоднородности создаются потоками точечных дефектов в процессе деформации [2]. Это как раз тот случай, когда за-рождение и рост ферромагнитных кластеров с помощью магнитных методов регистрируются на стадии предвыделений.…”

16Davydov D.I. et al. / Structure and magnetic properties of a nickel-based superalloy after deformation.http://dream-journal.org page 16÷28 The structure and magnetic properties of ChS-70 nickel-based superalloy samples have been compared after different types of deformation. The different behavior of the magnetic properties is governed by the difference in the structure resulting from deformation. High-temperature tensile tests and shear deformation under high pressure have been performed for ChS-70 alloy samples. Samples cut from different parts of a turbine blade after operation under forced conditions have been examined. The deformation of the Chs-70 alloy under operation increases magnetic susceptibility, which is due to the formation of complex defects of the crystalline structure inside the intermetallic particles (Ni 3 Al). Dynamical recovery during the high-temperature tensile tests leads to relaxation, elimination of crystal lattice defects, and the magnetic properties remain unchanged. Shear under high pressure causes a nanocrystalline structure in the alloy, a significant decrease in the degree of the long-range order in the intermetallic phase and the preservation of the paramagnetic state.
