采用搅拌摩擦焊接方法成功地焊接了Zr55Cu30Al10Ni5大块金属玻璃板。使用更宽的工具将闪光形成和肩部边缘的热量集中最小化，凹肩部表面的角度为3°。采用DSC、XRD、TEM和显微硬度分析了基体的微观组织和力学性能，分析了基体的结晶和搅拌区。结果表明，整个接头保持了非晶组织和原有的力学性能。
A Zr55Cu30Al10Ni5 bulk metallic glass plate was successfully welded below its crystallization temperature by friction stir welding. The flash formation and heat concentration at the shoulder edge was minimized using a wider tool and the angle of the recessed shoulder surface was 3°. To analyze the crystallization of the base material and stir zone, the microstructure and mechanical properties were analyzed using DSC, XRD, TEM, and micro-hardness. As a result, it was found that the amorphous structure and original mechanical properties were maintained in the whole joints.
