“…Whereas for the sample 3 in Fig 5d there is a substantial increase in sharp crystalline peaks that indicates a substantial increase of the crystalline phase in the Vit 1b material. These results concur with those reported in another investigation where it was demonstrated that the non-crystalline morphology of a Mg-based BMG could be retained after optimising the NS laser ablation process (Lin et al, 2012).…”

The capabilities of the component technologies together with some issues associated with their integration were studied. To validate the replication performance of the produced masters, a Zr-based BMG insert was used to produce a small batch of micro fluidic devices by micro-injection moulding. Furthermore, an experimental study was also carried out to determine whether it would be possible by NS laser ablation to structure the Zr-based BMG workpieces with a high surface integrity while retaining the BMG' s non-crystalline morphology. Collectively, it was demonstrated that the proposed process chain could be a viable fabrication route for mass production of polymer devices incorporating different length scale features.

“…Thus, laser manipulations of amorphous alloys attract interest as industrial processing method. Such, powder coating by amorphous layers [14,15], laser beam welding [6,8], laser surface hardening by the knock waves [16,17], laser microscopic treatment of the surface [18] and laser technologies for the preparation of the micro-and nano-structures were developed [19].…”

Zirconium based bulk metallic glasses are industrially valuable materials which commercial market grows rapidly. Surface modification of these metallic glasses by high-intensity lasers is relatively new and costly treatment promising great advantages over classical surface processing methods. In this work we perform the case study of surface modification of Zr$_{46}$Cu$_{36.8}$Ag$_{9.2}$Al$_8$ metallic glass by high-intensity millisecond laser beam. Our results suggest chemical deposition of atmospheric oxygen and nitrogen in the laser-melted surface area and its surroundings. Zirconium nitride layer was detected in the middle of laser-irradiated area. Nanocrystals embedded in the amorphous matrix were also formed on the surface. Overall, our findings suggest possibilities for improvement of mechanical characteristics of the studied metallic glass.

“…Nowadays, laser shock peening (LSP), as a new surface treatment technology, has been widely used in the national defense industry, machinery manufacturing, aerospace and other fields [1][2][3][4]. In the laser shock peening, high power density (GW/m 2 ) and short pulse width (ns) laser irradiate on the material surface, resulting in the vaporization of the material and the formation of plasma.…”
