Radiation strengthening and microstructure evolution in austenitic chromium-nickel steel under the effect of the irradiation of different types
Russian Metallurgy (Metally). 1997. No. 3. P. 74–79.
The results of the study of radiation-induced strengthening and microstructure evolution in the 0Kh18N10T austenitic stainless steel irradiated by neon ions (with energy of 230 MeV) and neutrons (En > 0.1 MeV) are presented. The experiments were performed in an inner beam of an U-400 cyclotron in Dubna and in an EWA reactor (Institute of Atomic Energy, Swerk, Poland). The dependence of the mechanical properties on the dose of irradiation-induced damage was determined. Changes in microstructure are studied by TEM, and the density of the aggregates of irradiation-induced defects was determined as a function of the dose. The data obtained are discussed in terms of mechanical properties and microstructure characteristics.

Numerous studies have provided compelling evidence that the probability distribution of avalanche sizes follows a power law, and that 1/f noise is present in the stochastic dynamics of landslides. We present a theoretical explanation of these phenomena within the framework of self-organized criticality theory, proposing a discrete-time model in the form of a sandpile cellular ...

A discrete-time model is presented for the self-organization of the X/Twitter social network to the edge of a phase transition, characterized by avalanche-like propagation of information in the network. The model is based on the analogy between the critical dynamics of the X social network and sandpile cellular automata with Manna rule on the Chung-Lu ...

Superconducting properties of metallic micro- and nanowires can be entirely different from those of bulk superconductors. Of particular interest is the nonequilibrium current-induced state of a quasi-one-dimensional superconducting channel. The most interesting phenomenon here is the stepped I–V characteristic, explained by a process known as phase slip center activation. If the origin of such step-like ...

Machine learning (ML) has become a powerful tool for accelerating the development of carbon-based supercapacitors;
however, most published models assume that a single predictive framework can describe both conventional
porous carbons and hybrid carbon electrodes. Here, we test this assumption using a comprehensive
benchmark dataset and an extended literature-curated dataset enriched with synthesis- and electrolyte-related
descriptors. Three ML algorithms ...

This paper compares the ranging precision of direct time-of-flight (dToF) and non-line-of-sight (NLOS) LiDAR architectures, both using a superconducting nanowire single-photon detector (SNSPD). Both systems operate at 1550 nm with a 50 ps pulsed laser and time-correlated single-photon counting (TCSPC). The dToF configuration achieved approximately 100 µm precision at 10 m, while the NLOS configuration achieved 500 µm precision for ...

Off-stoichiometric boron-doped chemically complex intermetallic alloys (CCIMAs) have recently emerged as a new avenue for overcoming the low temperature brittleness of ordered superlattices. However, their behavior at high temperatures remains unexplored. In this study, a novel (Ni39.6Co29.3Cr10Al15.8Ta3.3Nb2)98.5B1.5 CCIMA was prepared and its oxidation resistance over a wide temperature range (500 °C–950 °C) was studied. The ...
