Article ID: 1003-6326(2005)03-0612-03 Deformation of Zr41Ti14Cu12.5Ni10Be22.5 bulk amorphous alloy under isobaric pressure in super-cooled liquid region ZHANG Ke-qin(张克勤)1, LU Qi..., a number of complex multi-component bulk amorphous alloys with excellent glass forming ability(GFA) are developed[5-12]. The minimum critical cooling rate for glass formation has been reported to be about......

of muzzle dropped from heating position to the job position have very great influence on the amorphous forming ability. With higher heating temperature and the shorter time, super-cooled result can... will become much lower in the district of super-cooling liquid, thus bulk amorphous alloy could be obtained. From Fig.3, Tg and Trg are estimated to be 813K and 0.76, respectively. INOUE et al[10-12......
, then continuously decreases to 54 K for x=3 and 43 K for x=5. It is well known that higher ΔTx value means higher glass-forming ability[13], indicating that the super-cooled liquid can exist in a wide temperature... with diameter of 1 mm. It is found that all the samples exhibit distinct glass transition, followed by a broad super-cooled liquid region and then exothermic reactions due to crystallization. The glass......
