“…One of the possibilities to improve ductility in these materials is producing glass-matrix composites. Recent reports have discussed the formation of two-phased glassy composites in Ni-Ag-P [3], Fe-Cu-Si-B-Nb [4], Ag-Cu-Zr-Al [5], Ag-Ni-Nb [6] or many others. In these, alloys are produced using immiscibility occurring between the elements.…”

The aim of this work was to investigate the possibility of obtaining an amorphous/crystalline composite starting from Ni-Si-B-based powder grade 1559-40 and silver powder. The alloy was produced using arc melting of 95% wt. Ni-Si-B-based powder (1559-40) and 5% wt. Ag powder. Ingot was re-melted on a copper plate and observed while cooling using a mid-wave infra-red camera. The alloy was then melt-spun in a helium atmosphere. The microstructure of the ingot as well as the melt-spun ribbon was studied using light microscopy and scanning electron microscopy with energy dispersive spectrometry. Phase identification was performed by means of X-ray diffraction. The observations confirmed an amorphous/crystalline microstructure of the ribbon where the predominant constituent of the microstructure was an amorphous phase enriched with Ni, Si, and B, while the minor constituent was an Ag-rich crystalline phase distributed in a film along the melt-spinning direction.
