Abstract
The feasibility of bonding amorphous ribbons via explosive welding (EW) is demonstrated. With 20–120 layers of Fe78B13Si9 and Fe40Ni40P14B6 amorphous ribbons 25 µm thick and 10 cm wide, the plate samples are bonded by using two setups with a collision point velocity of 3900–4800 m/sec and a flyer plate velocity of 570–900 m/sec. The largest area of the bonded sample is 30 cm2. The microstructures of the samples are observed by optical microscopy and X-ray diffractometry. Based on the formation characteristics of amorphous alloys and heat-exchange characteristics during the EW process, a square-wave model for the temperature distribution across the interface is proposed. It can be used to explain the reasons for the samples keeping the amorphous state across the interface after explosive welding. The calculated results are in good agreement with the experiments.
