Fatigue strength of 30ХГСА–40ХМФА welded joints produced by rotary friction welding

Rotary friction welding (RFW) is used in the production of drill pipes for solid mineral prospecting. The need for the creation of the lightened drill strings for high-speed diamond drilling of ultradeep wells dictates the necessity of a greater focus on the study of a weld zone and setting the RFW technological parameters. This paper presents the results of experimental studies of a welded joint of a drill pipe of the H standard size according to ISO 10097, made of the 30ХГСА (pipe body) and 40ХМФА (tool joint) steels under the cyclic loads. The authors evaluated the influence of the force applied to the workpieces in the process of friction of the contacting surfaces (force during heating), and postweld tempering at a temperature of 550 °С on the cyclic life of welded joints, under the conditions of alternate tension-compression at the cycle amplitude stress of ±420 MPa. The study determined that with an increase in the force during heating, the microstructure changes occur in the zone of thermomechanical influence, contributing to an increase in the fatigue strength of welded joints. The authors identified the negative effect of postweld tempering on the fatigue strength of welded joints, which is expressed in the decrease in the number of cycles before failure by 15–40 %, depending on the magnitude of the force during heating. The optimal RFW mode of the specified combination of steels is determined, which provides the largest number of cycles before failure: the force during heating (at friction) Fh=120 kN, forging force Ffor=160 kN, rotational frequency during heating n=800 Rpm, and upset during heating l=8 mm. A series of fatigue tests have been carried out at various values of the cycle amplitude stress of the welded joint produced at the optimal mode and the 30ХГСА steel base metal; limited endurance curves have been plotted. It is shown that the differences in the limited endurance curves of the pipe body material (30ХГСА steel) and the welded joint are insignificant. The obtained results are supplemented by the microhardness measurement data and fractographs of fractured samples, revealing the mechanism of crack propagation under the cyclic loads

The impact of secondary mineral formation on Na-K-geothermometer readings: a case study for the Valley of Geysers hydrothermal system (Kronotsky State Nature Biosphere Reserve, Kamchatka)

The temperature in the Valley of Geysers (Kamchatka) geothermal reservoir calculated using the feldspar Na-K-geothermometer has been steadily increasing over the past 10 years on average from 165 to 235 °C, which is close to the temperature values of a hydrothermal explosion of the steam and water mixture. For the analysis of chemical geothermometers, TOUGHREACT-simulation was used, with the help of which the previously known Na-K feldspar geothermometer was reproduced on a single-element model and new formulas were obtained for three Na-K geothermometers: zeolite, smectite, and based on volcanic glass. Data of chemical analysis for the period 1968-2018, in which the chloride ion is considered as an inert tracer of geofiltration processes, indicates that after 2007 a significant inflow of infiltration water (its mass fraction is estimated from 5 to 15 %) into the Geyser reservoir. It is assumed that the Na-K increased values of the feldspar geothermometer are not the result of the temperature increase in the Geyser reservoir, but the effect of smectite water dilution

Population dynamics and demographic history of Eurasian collared lemmings.

BACKGROUND: Ancient DNA studies suggest that Late Pleistocene climatic changes had a significant effect on population dynamics in Arctic species. The Eurasian collared lemming (Dicrostonyx torquatus) is a keystone species in the Arctic ecosystem. Earlier studies have indicated that past climatic fluctuations were important drivers of past population dynamics in this species. RESULTS: Here, we analysed 59 ancient and 54 modern mitogenomes from across Eurasia, along with one modern nuclear genome. Our results suggest population growth and genetic diversification during the early Late Pleistocene, implying that collared lemmings may have experienced a genetic bottleneck during the warm Eemian interglacial. Furthermore, we find multiple temporally structured mitogenome clades during the Late Pleistocene, consistent with earlier results suggesting a dynamic late glacial population history. Finally, we identify a population in northeastern Siberia that maintained genetic diversity and a constant population size at the end of the Pleistocene, suggesting suitable conditions for collared lemmings in this region during the increasing temperatures associated with the onset of the Holocene. CONCLUSIONS: This study highlights an influence of past warming, in particular the Eemian interglacial, on the evolutionary history of the collared lemming, along with spatiotemporal population structuring throughout the Late Pleistocene

Design thinking: in the labyrinth of the concept

The article presents a critical analysis of the most common approaches to defining the concept of «design thinking» in Russian-language publications: a creative rather than analytical method for solving any problems; focus on the interests of the end user, innovation development strategy. However, in the context of the growing popularity of the term «design thinking», it is being blurred and devalued, which negatively affects the attitude towards design itself: design thinking, positioned as a publicly accessible activity, leads to a simplified understanding of the essence of design activity, this methodology and, often, its amateurish use

The algal composition and structure of the Yaitskoe lake (Samara Region, Russia)

We studied the phytoplankton of the Yaitskoe Lake (Samara region, Russia) from May to October 2009–2011. In this water body, there were 312 species and intraspecific taxa of algae. They belonged to nine taxonomic Divisions, 14 Classes, 22 Orders, 52 Families, and 108 Genera. A larger number of species, varieties and forms of algae belonged to the Chlorophyta, which included 37% of the total number of species and intraspecific taxa, followed by Bacillariophyta (21%), Euglenophyta (14%), and Cyanoprokaryota (12%). The other algae species number was less than 10% of the total species richness. The value of algae quantitative development was high in the Yaitskoe Lake during the three-year period. The values of abundance and biomass increased from spring to the end of summer, then there was a decrease. The level of trophic state was assessed as eutrophic. The abundance and biomass of algae were high during the study. The level of species diversity and evenness in phytoplankton community were assessed as high. Indices values, calculated by the phytoplankton abundance, were maximal at late spring. In summer, their values decreased. This was due to the increased dominance of blue-green algae (cyanoprokaryotes). The degree of cyanoprokaryota dominance decreased in autumn, while species diversity and evenness of the community increased. The indices, calculated on biomass, decreased from spring to early autumn. Their minimal values were during the «blooming» of water, and then gradually increased. Saprobiological analysis showed that this pond belonged to the β-mesosaprobic type, moderately polluted with Class III of water quality
