MODIFICATION EFFECT AND MECHANISM OF Sr, Na IN Al-Si ALLOY

Abstract

Abstract: Oxidation kinetics of Sr, Na in Al-Si melt is investigated. Modification mechanism of Sr and Na in Al-Si melt is discussed with theory of atomic hybridized orbit. The results showed that effective modification period of Sr is longer than that of Na because the atomic hybridized orbit of Sr is more stable than that of Na.

Key words: Al-Si alloy, Modification, Oxidation kinetics, Sr & Na, accuracy, boring, deep-hole, surface roughness, Ultrasonic vibration, weak stiffness
