Influence fluxes with different composition on the structure and mechanical properties OF Аl-7%Si silumin. Part 1

The paper presents the results of experimental studies AK7ch alloy before and after modification byindustrial modifier K2ZrF6 and foreign flux. It was shown that the modification AK7ch alloy leads to a uniformdistribution and reduction of the structural components, grinding and changing of the shape of Fe-containing phases. It is shown that all modified samples are characterized by an increase in mechanical properties
