Multicomponent Aging Al-Li-Based Alloys of the Latest Generation: Structural and Phase Transformations, Treatments, Properties, and Future Prospects
An overview of modern material science problems is presented for ultralightweight highmodulus commercial Al-Li-based alloys in historical retrospect. Numerous particular examples of the Soviet and Russian aviation whose various designs were made of these alloys confirm their successful innovative potential. The key regularities of multicomponent alloying are discussed for the master alloys and modern commercial Al-Li-based alloys of the latest generation; the features typical of their microstructures, phase composition, and properties formed during aging are analyzed. The main mechanisms of phase formation are generalized for standard thermal and thermomechanical treatments. Recent original achievements have been obtained in designing of unique structural and phase transformations in these commercial alloys by means of methods of severe plastic deformations followed by heat treatment and storage. Using the example of three Russian commercial alloys of last generation, the basic principles of creating and controlling an ultrafine-grained structure, the origin and growth of stable nanophases of various types and chemical composition that determine the physicomechanical properties of alloys are established. © 2022 by the authors.

Influence of ion irradiation on the structure and mechanical properties of extruded V95 alloy profiles after artificial aging
The effect of 10-keV Ar+ ion irradiation on the mechanical properties and structural and phase state of hot-pressed thin profiles 1.5 mm thick and made of an V95 alloy (Al-Zn-Mg-Cu system) after artificial aging (T = 140?C, 16 h) has been studied. Ion beam treatment of the alloy (j = 300 μA•cm-2, F = 1.9•1015 and 1.1•1016 cm-2) without heating the samples to significant temperatures (T < 35-50?C) has not been established to change the ultimate strength and yield strength; however, it increases the relative elongation by 1-2 %. Transmission electron microscopy has shown that irradiation changes the grain structure and the morphology of particles of the crystallization origin in the entire volume of quenched and artificially aged V95 alloy samples (1.5 mm thick). The irradiation does not affect the size and the volume fraction of fine strengthening η′- and η-phase particles. © 2019 IOP Publishing Ltd.

© 2016, Econjournals. All rights reseved. The relevance of the study is reasoned by the fact that the sustainability of innovative development cannot be fully estimated by using the parameters which are traditionally observed by the official statistical bodies, so it suggests the need to improve methodological solutions and technology economic interpretation as well as scaling of indicators’ values in this field. At the macro level there is a small number of indicators on the basis of which we can conclude about the stability of innovative development of economic systems at the meso-and macro level. In this regard, this article aims to formalize the process of sustainable innovation development on the basis of the parameters’ set formation of the innovations’ diffusion model and diagnosis of major economic systems’ development level. The leading method is the parameters’ set formalization of the quantitative model to estimate the level of economic systems’ innovative development based on managerial interpretation of descriptive statistics’ indicators of innovation activity in the framework of economic activities. Aset of quantitative parameters of 9 parametric model of economic systems’ innovative development level is formalized in the article, allowing to diagnose the impact of cyclical factors and the institutional environment that are not fully implemented in the existing macro- systems assessing the level of economic systems’ innovative development; methods of diagnosis and economic interpretation of the relevant indices and indicators’ levels are proposed. The material of this paper is of practical value for enterprises’ innovative activities regulators and monitoring agencies, for regional innovation infrastructure and transfer technology entities, for innovation-active enterprises, because on the basis of the obtained model the optimal solutions in the development of strategies for the upgrading of industries, regions, macro-economic system as a whole are possible

Селекция гороха овощного для консервной промышленности с мелким размером зерна
Relevance. Therefore, at present, varieties with an average seed size are used for the production of canned "green peas". In this regard, it is important to create varieties with a mass of 1000 seeds less than 150 g for the production of premium canned food.Methods. The object of research was the lines of hybrids of vegetable peas of different ripeness groups with a low weight of 1000 seeds.Results. At the initial stage of the work, plants with a low mass of 1000 seeds and green cotyledons were selected and brought to constant lines over several years. Over the years of sampling, the weather conditions were with sharp changes in temperature and precipitation. This made it possible to single out samples with low variability of the selected characters based on the totality of characters. In 2018-2019, the selected lines were studied according to the characteristics of productivity and manufacturability during the period of technical ripeness in the nursery of competitive variety testing of vegetable peas. To determine the duration of the technical ripeness period and its relationship with the yield, the green peas were harvested in three periods, starting with the minimum density indicators (34-35 units) and with an interval of three days. When determining the fractional composition of green peas, sample 4.12 was isolated, which received the varietal name Smaylik. Green peas of this variety had a fairly high uniformity and small grain diameter with a predominance of fractions of 5-8.5 mm and 8.6-9.9 mm. Sample 12.12 was close to Smaylik in its performance. According to the results of competitive variety testing, the Smaylik variety in 2019 was transferred to the State variety testing of the Russian Federation. Актуальность. В настоящее время для производства консервов «зеленый горошек» используются сорта со средним размером семян. Актуально создание сортов с массой 1000 семян менее 150 г для производства консервов премиум класса.Материалы и методы. Исследования проводили на опытном поле ФГБНУ ФНЦО (Московской область). Объектом исследований служили линии гибридов гороха овощного разных групп спелости с низкой массой 1000 семян.Результаты и обсуждение. На начальном этапе работы были отобраны растения с низкой массой 1000 семян и зеленым цветом семядолей и в течение нескольких лет доведены до константных линий. За годы отборов погодные условия были с резкими перепадами температур и осадков. Это позволило по совокупности признаков выделить образцы с низкой вариабельностью селектируемых признаков. В 2018-2019 годах выделенные линии изучали по признакам продуктивности и технологичности в период технической спелости в питомнике конкурсного сортоиспытания гороха овощного. Для определения продолжительности периода технической спелости и её связи с урожайностью, уборку зеленого горошка проводили в три срока, начиная с минимальных показателей плотности (34-35 единиц) и с интервалом в трое суток. При определении фракционного состава зеленого горошка выделился образец 4.12, который получил сортовое название Смайлик. Зеленый горошек этого сорта имел достаточно высокую выравненность и мелкий диаметр зерна с преобладанием фракций 5-8,5 мм и 8,6-9,9 мм. Образец 12.12 по своим показателям был близок к Смайлику. По результатам конкурсного сортоиспытания сорт Смайлик в 2019 году был передан на Государственное сортоиспытание РФ
