先进材料疑固实验室 Review Laboratory of Advanced Materials Solidification Eutectic solidification is the solidification of a liquid with eutectic composition. During eutectic solidification,two solid phases nucleate and then grow simultaneously. Eutectic solidification results in formation of eutectic structure. anced Matera 上浒充通大学 SHANGHAI JIAO TONG UNIVERSITY
