The results show that a lot of primary eutectic exists in the microstructure of the alloy as-cast, whose melting temperature is 478℃; Two processes were found during 470℃ homogenization, one is that the primary eutectic dissolves into the matrix, the other is that the primary eutectic transfo.
6Cu超高强铝合金的铸态组织中存在大量的非平衡凝固初生共晶体,其熔化温度为478℃;在470℃均匀化过程中该合金铸锭中的初生共晶体在向基体溶解的同时还转变成熔点约为490℃的产物;在470℃均匀化处理时间达到72h时,合金中的初生共晶体全部消失,但由初生共晶体转变而形成的熔点约为490℃的产物在470℃均匀化处理过程不能被完全消除。

Squeeze casting can also refine the microstructure of ZA27(alloy),increase the amount of eutectic and reduce the size of them.
挤压铸造使合金的组织细化,并使组织中共晶体的数量明显增多,尺寸减小。

By calculation of thermodynamics, analysis of crystal structure and study of TEM and eletron probe, it is first discovered that SiO_2 can be acted as one of the heterogeneous nuclei for lamellar intergrowth eutectic(austenite and cementite) crystallizing in modified as-cast medium manganese steel.
对变质铸态中锰钢进行热力学计算、晶体结构分析,透射电镜与电子探针研究,发现SiO_2完全可以作为层片状共生共晶体(共晶两相为奥氏体与合金渗碳体)的非自发核心。
