采用铜模铸造法制备出一系列Zr-Al-Ni-Cu块体非晶合金，其脆性参数值分别采用Arrhenius和Vogel-Fulcher-Tammann (VFT)方法进行计算。结果表明，这些非晶合金具有低的脆性参数值，其原因可能与网络状的微观结构有关。另外，Zr-Al-Ni-Cu合金的脆性参数值可以通过Zr含量进行调整，当Zr含量接近54%(摩尔分数)时，Zr-Al-Ni-Cu合金，即Zr 54 Al 13 Cu 18 Ni 15合金的脆性参数值最小，约为13。

Zr-Al-Ni-Cu bulk metallic glasses (BMGs) were developed and their fragility parameters (m) were calculated by Arrhenius and Vogel-Fulcher-Tammann (VFT) equations. The results show that the m values of the Zr-Al-Ni-Cu BMGs derived by Arrhenius equation are in agreement with the corresponding m values derived by VFT equation. These Zr-Al-Ni-Cu BMGs characterize in low m values. The low m values for these BMGs would be due to their network microstructures. In addition, the m values of Zr-Al-Cu-Ni BMGs could be obtained by regulating Zr content. The composition of Zr-Al-Cu-Ni BMGs with the lowest m value would be near 54%Zr (mole fraction) because the m value about 13 of Zr 54 Al 13 Cu 18 Ni 15 BMG is the lowest among these Zr-Al-Ni-Cu BMGs developed.
