为了建立块体非晶合金的冶金连接技术，我们尝试了采用摩擦焊和脉冲焊两种焊接方法对具有宽过冷液相区和高非晶形成能力的Pd40Ni40P20和Zr55Al10Ni5Cu30块体非晶合金进行焊接。我们首次成功地用这两种方法连接了大块金属玻璃。在界面和热影响区没有观察到结晶。界面处无明显缺陷，表明大块非晶合金实现了冶金结合。焊接块体金属玻璃的抗拉强度与母体块体金属玻璃的抗拉强度相同。
In order to establish metallurgical bonding technology of bulk metallic glasses, we have tried to weld Pd 40 Ni 40 P 20 and Zr 55 Al 10 Ni 5 Cu 30 bulk metallic glasses having a wide supercooled liquid region and high glass forming ability by two welding methods of friction and pulse-current. We have for the first time succeeded in joining bulk metallic glasses by both methods. No crystallization was observed in the interface and heat-affected zones. No visible defect was recognized at the interface, showing an achievement of metallurgical bonding of bulk metallic glasses. The tensile strength of the welded bulk metallic glasses was the same as that of the parent bulk metallic glasses.
