为了增大大块非晶合金的尺寸，采用搅拌摩擦焊方法成功地焊接了两块Cu36Zr48Al8Ag8大块非晶合金，焊接过程中未出现明显的晶化现象。研究了搅拌摩擦焊对非晶合金显微组织和力学性能的影响。采用X射线衍射（XRD）和扫描电子显微镜（SEM）研究了BMG中晶粒的变化。采用纳米压痕法分析了非晶基体的变化。测试搅拌摩擦焊前后搅拌区的显微硬度，探讨搅拌摩擦焊后力学性能的变化。结果表明，搅拌摩擦焊后，非晶合金中原有的Al3Zr颗粒得到细化，在非晶基体中出现了一些平行于旋转方向的空洞。此外，由于非晶基体的结构弛豫，与铸态样品相比，搅拌区的显微硬度升高约50 Hv。
In order to enlarge the size of bulk metallic glasses (BMGs), two Cu36Zr48Al8Ag8BMGs plates were successfully welded by friction stir welding (FSW) without obvious crystallization. The effect of friction stir welding on microstructure and mechanical properties of the BMGs was investigated. X-ray diffraction (XRD) and scanning electron microscope (SEM) were used to evaluate the changes of the crystalline particles in the BMGs. Nanoindentation was applied to analyze the changes of the amorphous matrix. Micro-hardness of the stir zone before and after FSW was tested to explore changes of the mechanical properties. Results show that the original Al3Zr particles in the BMGs were refined and some cavities parallel to the rotating direction of the pin were observed in the amorphous matrix after FSW. Furthermore, micro-hardness of the stirred zone rises approximately 50 Hv compared with the as-cast sample due to structure relaxation of the amorphous matrix.
