Ti-Nb POWDER ALLOYS IN THE ADDITIVE TECHNOLOGIES

Nanoscience and Technology An International Journal (2017)

Zh. G. Kovalevskaya Yu. P. Sharkeev Margarita A. Khimich М. А. Корчагин В. А. Батаев

The Ti–Nb powder alloy with mass content of 40% and 45% Nb was obtained from Ti and Nb powder mixture in a planetary ball mill in an argon atmosphere. The structure, grain-size distribution, and phase composition of the powder alloy obtained are determined by the time of mechanical alloying. With increase in the alloying time from 3 to 20 min, the average size of the particles formed increases from 41 to 67 μm and then decreases twice at the 25th min of alloying. The shape of the particles changes from shells to pellets. With increase in the alloying time, the quantity of the total solid solution of Ti and Nb components increases in the alloy. A monophase β-alloy is formed in the powder alloy containing 40 wt.% of Nb at alloying time of 20 min. A monophase β-alloy is formed in the powder alloy with 45 wt.% of Nb at alloying time of 15 min. Composition with the 45 wt.% Nb obtained at 15 min alloying time is recommended for using the powder alloy in the process of selective laser melting. Optimization of the powder alloy grain-size distribution obtained requires the sieving of the powder large fraction.

Effect of annealing in the range of thermal stability on structure peculiarities of steel Fe-Mo-Nb-V-0.08C processed by high-pressure torsion

Letters on Materials (2015)

Е. Г. Астафурова Galina G. Maier Вера Сергеевна Кошовкина E. Melnikov E. V. Naydenkin

We studied the effect of annealing in the range of thermal stability on the structure of the steel Fe-Mo-Nb-V-0.08C processed by cold high-pressure torsion. After annealing at 500 ° C, the average size of the structural elements (microcrystallites, d = 112 nm) and their size distribution vary slightly compared to the state after torsion, and the microhardness increases up to 6.4 GPa (6.0 GPa after high-pressure torsion). After annealing of the steel, a partial relaxation of the structure and boundaries occurs, as well as the nucleation of thermally activated nuclei of recrystallization, the size of which is close to the size of the microcrystallites and subgrains formed under high-pressure torsion. Along with the particle hardening, this leads to the maintenance of high values of microhardness and submicrocrystalline character of the structure in steel after annealing at 500 °C.

Osseointegration of alumina bioceramic granules: A comparative experimental study

AIP conference proceedings (2016)

В. В. Рерих A. R. Avetisyan A. M. Zaydman K. A. Anikin В. А. Батаев

To perform a comparative analysis of osseointegration of bioceramic alumina-based granules, hydroxyapatite-based granules, and deproteinized bone granules. The experiment was conducted on 52 adult male Kyoto-Wistar rats weighing 350 to 520 g. The animals were divided into five matched groups that differed only in the type of an implanted material. The granules were implanted in the lumbar vertebral bodies and in the distal right femur of each laboratory animal. Two months after surgery, the animals were euthanized, followed by tissue sampling for morphological studies. An examination of specimens from the groups with implanted alumina granules revealed the newly formed trabecular bone with remodeling signs. The bone tissue filled the intragranular space, tightly adhering to the granule surface. There was no connective tissue capsule on the border between bone tissue and alumina granules. Cylindrical bioceramic alumina-based granules with an open internal channel have a higher strength surpassing than that of analogs and the osseointegration ability close to that of hydroxyapatite and deproteinized bone granules.

Comparison of tungsten modification after irradiation at different facilities for PSI studies

AIP conference proceedings (2016)

A.A. Shoshin A. S. Arakcheev Ivan A. Bataev В. А. Батаев А. В. Бурдаков

Results from different facilities for plasma-surface interaction (PSI) studies are compared and their relevance to each other and conditions of ITER transient events are discussed. For PSI studies different types of devices were used including open traps, tokamaks, linear plasma machines including quasi-stationary plasma accelerators, electron beams and lasers. The same damage thresholds were demonstrated with different techniques. At energy loads corresponding to ITER transient events (edge localized modes (ELMs), disruptions, etc.) only macroscopic erosion mechanisms are important. They are cracking, droplet formation and macroscopic mass losses of the target. Cracking occurs during cooling stage after irradiations. Details of plasma stream parameters are of secondary importance for cracks formation; only target temperature plays a role. Macroscopic mass losses strongly correspond with melting of a thin surface layer and heat loads play a key role for melting. Heat flux defines the targets surface erosion.

Structural State, Phase Composition and Mechanical Properties of Wear-Resistant Cast Iron Modified by Ultrafine Powders

Advanced materials research (2013)

Anna Zykova И. А. Курзина Д. В. Лычагин А. V. Chumaevsky А. А. Качаев

The paper explores the effect of a modifier based on ultrafine powders of refractory metal oxides on the change of structural state, phase composition and mechanical properties of cast iron of ИЧХ28Н2 (Russian grade). It was shown that the modifier added to the melt does not change the phase composition of ferrite-austenitic matrix and carbides and is not carbide-forming. Material microstructure changes only due to the presence of a large amount of crystallization nuclei during the casting cooling. It was established that the modification increases the ultimate stress limit by 53%, plasticity by 10.7%, corrosion resistance by 15%, and leads to the reduction of friction factor and linear wear due to the decreasing of structural elements: carbide phase and austenitic-carbidic eutectic.

Observation of the tungsten surface damage under ITER-relevant transient heat loads during and after electron beam pulse

AIP conference proceedings (2016)

A. A. Vasilyev A. S. Arakcheev Ivan A. Bataev В. А. Батаев A. V. Burdakov

Wide-area (2 cm2) high-power (up to 7 MW) submillisecond electron beam source was applied for generation of intense pulsed heat loads on tungsten sample. Various diagnostics sets were used for in-situ research of the surface damage: IR imaging of the front view of the target, capturing of the reflection pattern of continuous wave laser radiation, recording of intensity of thermal radiation from several spots of the surface. Sample was exposed to a various heat loads near and above melting threshold. Formation of the crack network on the surface and its development with successive pulses was observed. Two-dimensional temperature distribution was obtained after heating at the cooling stage. Melting and spalling of material were shown on severe damaged target. Propagation of the cracks along the surface at a depth of 0.1 – 0.2 mm was revealed with transverse microsections. Circular motion of the molten layer was found with subsequent exposures.

DETERMINATION OF THE CONNECTION BETWEEN THE STRUCTURE OF CARBON FIBER SAMPLES AND THE PARAMETERS OF ACOUSTIC EMISSION SIGNALS DURING SIMULTANEOUS STATIC AND THERMAL LOADING

Kontrol Diagnostika (2019)

L. N. Stepanova В. А. Батаев В. В. Чернова

The effects of positive and negative temperature and static load on the main informative parameters (structure coefficient, partial energy, location) of acoustic emission (AE) signals, which determined the mechanism for changing the structure of carbon fiber and the beginning of its destruction, are investigated. Tests of specimens of carbon fiber T800, made of nine monolayers with laying [±45/90/О3/90/±45], size 600x100x0.9 mm. Each sample was subjected to static loading and the effects of positive (+20, +40, +60, +80, +100 °С) or negative (–20, –40, –60, –80 °C) temperatures in the area of the concentrator in the form of a 12 mm diameter hole. Using fractography, changes in the structure of carbon plastic from the applied static load and temperature and changes informative parameters were analyzed. It was shown that the lamination of the material with simultaneous exposure to static load and temperatures from –80 to –20 °C and from +60 to +100 °C corresponded to an increase in the structural coefficient and partial energy, which caused an energy shift in the frequency range 125…250 kHz. Under the same static loads, but temperatures of +20 and +40 °C, informative parameters took on minimal values, that meant the energy was shifted to the frequency range 250…500 kHz, characterized the crumbling of the matrix and breaking of the fibers without lamination of the CFRP. Under all temperature conditions, the location of the signals began in the hole area and spread in the direction of the static load. The detection the disturbance of the CFRP structure by the informative parameters of AE signals makes it possible to reduce the risk of emergency situations during working of the composite construction.
