| 1 | Compression behaviour of Pd39Ni10Cu30P21 bulk metallic glass up to 23.5Gpa显示文摘The compression behaviour of Pd39Ni10Cu30P21 bulk metallic glass is ivestigated at room temperature up to 23.5GPa using in situ high pressure energy dispersive x-ray diffraction with a synchrotron radiation source.Pressure induced strucural relaxation of the bulk metallic glass is exhibited within the pressure range.It is found that below about 5GPa,the existence of excess free volume contributes to rapid structural relaxation,which gives rise to rapid volumetic change.Under higher pressure,further relaxation results in structural stiffness. | LMWang ZJZhan JLiu LLSun GLi WKWang | 2001 | Beijing Synchrotron Radiation Facility2001，，2： | 0 |
