METHOD OF PRODUCING ALUMINIUM ALLOY-BASED COMPOSITE

摘要

FIELD: metallurgy.SUBSTANCE: base is fused to add thereto a composition including reinforcing particles AlOto form Al ply made by mechanical activation on their surfaces, obtained by being poured into the mould. Al ply in mechanical activation is subjected to cold working. AlOparticles are shaped to 50-40 mcm and introduced into the melt as-preheated to temperaturewhere tis aluminium fusion temperature, in amount of 15-20% of melt mass. Note here that silumin can be used as said base.EFFECT: higher breaking strength of cast composite.5 cl, 3 tbl
