Abstract
The paper introduced the preparation technology for bulk amorphous alloys. The samples were prepared by using the vacuum arc furnace, and the melt was processed by three different methods. The crystalloids of the samples were analyzed by using X - ray diffraction technology. The results showed that the compound oxide glass composed of B2O3 and Na2SiO3 reacted with some elements in the melt, therefore, it wasn´t favourable for coating the Zr66Al9Ni9Cu16 alloy, hence hindering the formation of the amorphous state. The fluorides composed of CaF2(45%), A1F3(50% ) and CaO (5%) and frace Ti02 reacted with some elements in the melt, so they were not suitable for purifying the Zr66Al9Ni9Cu16 alloy. High vacuum degree of equipment and high purity of the raw and processed materials were the important factors for to promoting the melt to form the amorphous alloy.
