Thermodynamic properties of alloys of the manganese-silicon system in the ranges of existence of the silicides “Mn9Si9” and “Mn6Si”

Conclusions The Gibbs energy, enthalpy, and entropy of formation of phases based on the compounds Mn₉Si₂ and Mn₆Si at 690–850°C have been determined by measuring the emf's of concentration galvanic cells.Translated from Poroshkovaya Metallurgiya, No. 7(235), pp. 67–70, July, 1982.     

Development of controllable spherical fluid friction hinges for exact spatial mechanisms

This paper focuses on the development of a special method for determining the workspace of hexapods. For this purpose, the ranges of possible angle positions of the hexapod-mechanism were determined and a controllable spherical hinge structure was designed. Moreover, the characteristics of the individual aero- and hydrostatic bearing elements and the effect of the single factors on the characteristics of a bearing element were determined; the bearing reaction was controlled by applying pressure with a working fluid. At the same time, the general control characteristics of the bearing element were defined. The controllable spherical aero- and hydrostatic bearing was calculated and designed on the basis of the Monte Carlo method.     

Physicochemical Interactions in Systems Formed by Trivalent REM with Group IV p Elements. Part 1. Intermetallic Compounds

A systems approach has been used in the analysis of the number, stoichiometry, and crystal structures of compounds formed by REM with group IV p elements. General trends and differences between the intermetallides have been identified. The existence and crystal structures are predicted for certain compounds not observed by experiment.
