Formation of Gas Pores in Amorphous Large-Diameter Wires Prepared by the Ulitovskii–Taylor Method

The peculiarities of the gas release during melt solidification of cobalt alloy amorphous wires 50–80 μm in diameter, which are prepared by the Ulitovskii–Taylor, are considered. The results are compared with the pore-formation mechanism that takes place during the solidification of ingots fabricated by different technologies. The number of low-strength areas in a long amorphous wire, which are caused by local gas porosity, can be decreased using melt refining vacuum technologies.
