Interfacial analysis of the ex-situ reinforced phase of a laser spot welded Zr-based bulk metallic glass composite
چکیده انگلیسی


• An ex-situ Zr-based BMG composite was laser spot welded.
• The interfacial regions of the RPs located at PM, WFZ and HAZ were investigated.
• The RPs in the PM, WFZ and HAZ were all covered by a ZrCu interfacial layer.
• Due to different formation processes, those layers show the different morphology

To study the interfacial reaction of the ex-situ reinforced phase (Ta) of a Zr-based ((Zr48Cu36Al8Ag8)Si0.75 + Ta5) bulk metallic glass composite after laser spot welding, the interfacial regions of the reinforced phases located at specific zones in the welds including the parent material, weld fusion zone and heat affected zone were investigated. Specimen preparation from the specific zones for transmission electron microscopy analysis was performed using the focused ion beam technique. The test results showed that the reinforced phases in the parent material, weld fusion zone and heat affected zone were all covered by an interfacial layer. From microstructure analysis, and referring to the phase diagram, it was clear that the thin layers are an intermetallic compound ZrCu phase. However, due to their different formation processes, those layers show the different morphologies or thicknesses.
