Π³ΡΠ°Π½ΠΈΡThe development of the modern nuclear industry leads to the need to create materials that
operate at high temperatures, high mechanical loads, and aggressive contact environments. Alloy
47Π₯ΠΠ is recommended for use in nuclear reactors, as it has high resistance to plastic deformation and
relaxation resistance under conditions of static and cyclic loading, low elastic hysteresis, high fatigue
strength and high corrosion resistance.
The article presents the results of a study of changes in the mechanical properties, phase composition
and structures of the industrial alloy 47Π₯ΠΠ after aging using the following methods: Xβray diffraction
analysis, microhardness measurements, tension in a tensile testing machine.
The dependence of microhardness on the aging time interval has been established. The maximum high
microhardness was recorded on the samples after aging. The dependences of the ultimate strength and
relative elongation of the studied samples on the aging time were revealed. In this work, Xβray diffraction
patterns of the 47Π₯ΠΠ alloy were analyzed and a cluster model of grain boundaries was propose
Investigation of Structural-Phase States and Features of Plastic Deformation of the Austenitic Precipitation-Hardening Co-Ni-Nb Alloy
This article presents the results of investigation of the inο¬uence of holding temperature
during the quenching process on the microstructure and superplasticity of the Co-Ni-Nb alloy.
Temperature-strain rate intervals of the deformation of the superplasticity effects are stated.
The optimal regimes of the preliminary treatment by quenching and rolling as well as the routine of
the superplastic deformation of the Co-Ni-Nb alloy are deο¬ned. The interval of the temperatures
of the precipitation, morphology, composition, type and parameters of the lattice of the secondary
phase, which appears after the annealing + rolling (to 90%) Co-Ni-Nb alloy, are determined
