The Problem of Public Consciousness in Soviet Philosophy and Sociology

The article gives a theoretical survey of the concepts of social consciousness and depicts the history of formation of this concept in the 1950–70s in the works of Vladislav Kelle and Matvey Kovalzon, Evald Ilyenkov, Vasily Tugarinov et al. The philosophy of this period was characterized by the antinomy between the increasing dogmatism of diamat/histmat and the  tendency towards convergence with world philosophical thought. The  struggle between ideological and scientific attitudes in Soviet humanities intensified. The scientific spirit permeated through the formation of  sociology and its increasing influence at both empirical and theoretical levels of analysis. During this period the problems of dialectics of individual and social consciousness, forms of social consciousness and mechanics of their functioning, correlation of social consciousness with public opinion, etc., are  under investigation. Much attention is given to the debate on the nature of  the ideal, which Ilyenkov explicitly linked to social consciousness. The opposition of natural scientific and philosophical approaches to the study of  consciousness is considered. The article draws attention to the scientific breakthroughs of the time: the problem of consciousness for the first time is  discussed in the light of the achievements of computerization in the 1960s and the problem of creating artificial intelligence. Three main approaches to  the study of social consciousness are considered: ontological, epistemological and sociological. The problem of social consciousness has  been actively discussed in Soviet philosophical literature since the late 1950s (although some studies were conducted even in the prewar period). At this time, there appear works in which social consciousness is interpreted not only as a reflection of social being, i.e. of the socio-economic structure of society, but also as a relatively independent phenomenon that requires multidimensional study and has a reverse effect on people’s material relations. Such an approach opened up the possibility of sociological analysis  of consciousness. The key concept of Soviet sociology is public opinion, understood as a peculiar state of public consciousness. Thus, the methodological foundations of empirical sociology, which aims to study public opinion, are laid. Boris Grushin discovers the specificity of public  opinion in its neutrality, equal acceptability for all social classes. The scholar regards sociological research as an effective tool for the formation of civil society and increasing its self-consciousness. The article shows the specificity  of the concept of public consciousness in Soviet sociology, including  empirical research based on mass interviews and study of public opinion

Mechanical behavior and microstructure evolution of a Ti-15Mo/TiB titanium–matrix composite during hot deformation

A Ti-15Mo/TiB titanium–matrix composite (TMC) was produced by spark plasma sintering at 1400◦C under a load of 40 MPa for 15 min using a Ti-14.25(wt.)%Mo-5(wt.)%TiB2 powder mixture.

Microstructure evolution of commercial-purity titanium during cryorolling

Electron backscatter diffraction and transmission electron microscopy have been used to analyze the microstructural evolution of titanium during rolling at a cryogenic temperature (T = –196°C). It has been found that intensive twinning at the cryogenic deformation temperature accelerates the kinetics of micro structure refinement. The quantitative analysis of microstructure evolution in titanium upon cryorolling has shown that structure evolution is mainly related to mechanical twinning in the initial stages cryorolling is discusse
