| 摘 要： | With the development of multicomponent Zr-based glass bulk metallic glasses(BMGs) with a larger geometry by a conventional casting process with a low coolingrate[1—4], high pressure, which is the simplest way to vary the interatomic distance ofsubstance and thus change its physical properties, has been employed as an importantmeans to investigate structural relaxation and the crystallization of the BMGs[5]. Relativeto crystalline, metallic glasses have excess free volume, which will annihil… |

| Abstract: | The compression of a Zr41Ti14Cu12.5Ni10Be22.5 bulk metallic glass (BMG) is investigated at room temperature up to 24 GPa using in-situ high pressure energy dispersive X-ray diffraction with a synchrotron radiation source. The pressure-induced structural relaxation is exhibited. It is found that below about 8 GPa, the existence of excess free volume contributes to the rapid structural relaxation, which gives rise to the rapid volumetric change, and the structural relaxation results in the structural stiffness under higher pressure. |
| Keywords: | bulk metallic glass high pressure structural relaxation synchrotron radiation. |
