Description

technical field [0001] The invention relates to the technical field of amorphous alloy welding, in particular to a system and method for laser-assisted preparation of bulk amorphous alloys. Background technique [0002] Due to its unique structure and excellent performance, amorphous alloys have important applications and supporting functions in high-tech fields such as energy, information, and national defense. However, the system of amorphous alloys is limited, and the size that can be synthesized is limited. The current commercial amorphous alloys are mostly at the centimeter or millimeter level, and decimeter-level amorphous alloys are rarely reported and commercialized, which seriously restricts amorphous alloys. wide application. [0003] Amorphous alloys have viscous flow behavior at the temperature of the supercooled liquid phase region. At this time, the combination of amorphous alloys can be realized by using its superplastic forming characteristics to complete th...
