| 英文摘要 | Secondary phase particles (SPPs) in a Ge-addition modified Zircaloy-4 alloy subjected to beta-phase region solution treatment was investigated in detail by transmission electron microscopy to acquire a better understanding on the microstructure of this new zirconium alloy. Result revealed that a novel type of SPPs with core-shell structure were frequently observed in this alloy, in which the "core" and "shell" structures were separately identified as primitive tetragoanl Zr3Ge phase and Zr(Fe,Cr)(2) Laves phase with a hexagonal close-packed (HCP) structure. The orientation relationship between the Zr3Ge core, Zr(Fe,Cr)(2) shell structures and the surrounding matrix were investigated and can be approximately described as [115](Zr3Ge)vertical bar vertical bar[11 (2) over bar(6) over bar](Zr(Fe,Cr)2)vertical bar vertical bar[11 (2) over bar3](alpha-Zr). It was strongly suggested that the gradient of Ge concentration occurred during the subsequent beta-phase region annealing affected the phase stability of Zr(Fe,Cr,Ge)(2) nanophase in the as-cast Ge-addition modified Zr-4 alloy, thereby causing the formation of Zr3Ge/core-Zr(Fe,Cr) (2)/shell microstructures. The knowledge attained from this study, shedding new lights on the formation mechanism of these novel core-shell SPPs, would also greatly benefit the understanding on the formation of similar composite precipitates in other alloys.
