Effect of Low-Melting Metals (Pb, Bi, Cd, In) on the Structure, Phase Composition, and Properties of Casting Al–5% Si–4% Cu Alloy

Resumo

The effect of low-melting metals (Pb, Bi, Cd, In) on the structure, phase composition, and properties of the Al–5% Si–4% Cu alloy was studied using calculations. Polythermal sections have been reported, which show that the considered systems are characterized by the presence of liquid regions and monotectic reactions. The effect of low-melting metals on the microstructure and hardening of base alloy in the cast and heat-treated states has been studied.
