Study of change in the scm's strength properties depending on the aqueous-clay suspension's concentration and muscovite's amount in its composition

Текст статьи не публикуется в открытом доступе в соответствии с политикой журнала.This article represents the results of the study of change in aqueous clay suspensions' (ACS) electrostatic properties depending on muscovite's concentration in their composition. The influence of ACS' concentration and muscovite's varied amounts in the composition of mechanically activated bentonite clay (Chernogorskoe field) used as a coupling agent in molding sand mixtures for steel and cast ironcasting, on the mixture's strength properties has been studied. The increase in the sand-clay mixture's (SCM) strengthproperties and gas permeability depending on the ACS's and muscovite's concentration has been establishe

THE COMPOSITION DEVELOPMENT AND TECHNOLOGICAL ASPECTS OF OBTAINING A NEW ALLOY BASЕD ON PALLADIUM

Текст статьи не публикуется в открытом доступе в соответствии с политикой журнала.The aim of this work is to develop a new solder with a lower melting temperature, relative to standard palladiumbased alloys, and improved technological properties using a three-component system additionally doped with boron. As a theoretical basis used approach to the analysis of complex systems developed by Professor Biront V.S. An experimental testing of boron was carried out at a content of 2.2 to 3.1 Wt% as a eutectic-forming substance in solder alloys of palladium. The methodology and technological modes of obtaining a new palladium-based solder alloy with a melting point of 1200 °C are also presented. Tests of the new alloy performed in the conditions of jewellery production gave positive results, on the basis of which its final composition was determined. This methodology was applied in the development of new compositions for noble metal alloys, which are protected by Russian and Eurasian patents

Design analysis of the thermal condi-tions for continuous casting and extru-sion based on a conform unit with hori-zontal mold wheel

The proximity mathematical model of complex heat exchange has been developed in the area of a conform unit a with horizontal mold for the continuous casting and extrusion of non-ferrous metals. The dynamics of the lead alloy extrusion have been studied at an experimental laboratory unit. The design temperatures for metal and elements of a prototype unit have been identifie
