It is shown that modification of steel with bariumstrontium carbonates promotes grinding of carbide impurities and decrease of their quantity in cast condition.
.
The aim of the work is development of new compositions of aluminium alloys with refractory metals of transition group and cremnium due to range extension of alloying at usage of high speed of melts cooling.
.
The mechanism of silumins structure formation on the basis of data of thermal, metallographic, microentgenospectral analysis is discussed.The theoretical conclusion is that crucial role in structure formation of eutectic belongs to Si-phase.
.
The way of alloying of sleeve cast iron with copper is offered. This technology will enable not only to stabilize of qualitative characteristics of cast slugs, but to reduce the expenses for alloying due to using of secondary materials as well.
.
The regularities of phase conversions in metal-oxide compositions on the basis of aluminium and silicon oxide with the purpose of silumins synthesis by means of direct restoration of aluminium silicon are studied.
.
It is shown that the received complex of mechanical and technological characteristics of alloy AK9 after processing of melt with investigated fluxes and preparations can be recommer ded for use in plant conditions that will enable the increase of ecological safety of color-founding production.
.
The results of investigations of consumer characteristics of separation coverings mainly used at the enterprises of the Republic of Belarus for moulds of aluminium alloys die casting are given in the articles.
