| Abstract Scope |
In this study, the metallic glass micro-wires which had micrometer scale in diameter with circular cross section were produced by melt-extraction method. Various compositions of metallic glasses, such as Co-based, Ni-based, Fe-based and Cu-based amorphous alloy wire, were synthesized using by melt extraction method, respectively. The metallic glass layers were deposited using laser melting additive manufacturing technique to investigate the effect of laser power on the deposition of metallic glass micro-wires. It was found that the mean width of deposited layer is expanded with increasing laser power attributed to a change in the wettability. The micro-hardness value of metallic glass deposited layer was higher in low power deposition. The reliability for the optimization of processing parameters to control micrometer scale deposition by metallic glass wire is also evaluated. |
