secondary solid solution

TEM, SEM, WDX EDX and selected area electron diffraction are used to study th secondary crystalline phase in Al_2O_3 ceramics containing 0.1& 0.5wt% MgO as solid solution.

应用TEM、SEM、WDX、EDX及选区电子衍射，对掺入0.1&0.5wt%MgO的微晶氧化铝陶瓷因固溶而形成的第二结晶相进行研究。

Results show that all the alloys consist of a V-based solid solution main phase with bcc structure and a C14 laves secondary phase with hexagonal structure.

结果表明，当无La替代时，合金主要含有BCC结构的固溶体相以及少量Laves相。

It was found that a cobalt-based solid solution with a face-centered cubic crystal structure is presented accompanied by the secondary phase M_7C_3 with a hexagonal crystal structure in the cobalt-based alloy coating.

结果表明，堆焊合金层主要是由面心立方的γ（Co）和六方结构的M7C3构成，并且在钴基固溶体中存在着许多堆垛层错。
