【 摘 要 】

Influence of melting conditions on the structure of AL30 alloy has been studied. To this end, the temperature dependences of physical properties of liquid alloy has been investigated. In is shown, that the formation of the microhomogeneous and the equilibrium alloy structure during melting process leads to significant decreasing of amounts of eutectic silicon. However, the amounts of primary α-aluminum solid solution and intermetallic compounds with dendritic form are increasing. Such treatment leads to decreasing of size of primary α-aluminum solid solution particles. On the base of experiments the physical model of aluminum-silicon alloy solidification was proposed.
