Formation of new materials based on cast aluminum alloy

We show the dynamic formation of composite materials using the polycrystalline cast alloy Al + 12% Si as the example. The volume fraction of the synthesized framework (“influence zones”) of the composite material has been estimated to be at a level of 11%. Upon the introduction of lead a material practically insoluble under the experimental conditions was synthesized in the framework. Upon the introduction into the Al + 12% Si cast alloy of silicon carbide particles, we obtained a material with a specific corrosion exceeding by a factor of 5.6 the given index of the source matrix material.[ 1 – 7 ]
